H4BZTXM9N6MC Mikrotik command actually almost the same as the existing command linux, mikrotik because basically this is a Linux kernel, the result of processing back from the Debian distribution of Linux. Use the same command shell, such as saving the command, simply use the TAB key on the keyboard then a long command, no longer need to be typed, simply type the beginning of the command is called, will automatically display the Shell will own commands respect. For example IP ADDRESS command in mikrotik. Enough just type in the IP ADD spaced press the TAB key, then the automatic shell will recognize and translate the IP ADDRESS command.
Let us continue with the introduction of this command. Once logged in, check the condition of the interface or ethernet card.
1. Looking at the condition of the interface on Router Mikrotik
[Admin @ MikroTik]> interface print
Flags: X - disabled, D - dynamic, R - running
# NAME TYPE RX-RATE TX-RATE MTU
0 R ether1 ether 0 0 1500
1 R ether2 ether 0 0 1500
[Admin @ MikroTik]>
If there is an X interface (disabled) after the number (0.1), then check again etherned card, should be R (running).
a. Renaming interface
[Admin @ MikroTik]> interface (enter)
b. To rename a Public Interface ether1 (or whatever his name), then
[Admin @ MikroTik] interface> set 0 name = Public
c. Likewise for ether2, say his name changed to Local, then
[Admin @ MikroTik] interface> set 1 name = Local
d. or just from the position of the root directory, use the sign "/", without quotes
[Admin @ MikroTik]> / interface set 0 name = Public
e. Check again if the interface name had been changed.
[Admin @ MikroTik]> / interface print
Flags: X - disabled, D - dynamic, R - running
# NAME TYPE RX-RATE TX-RATE MTU
0 R Local ether 0 0 1500
1 R Public ether 0 0 1500
2. - Change the default password
To change the default password security
[Admin @ Mikrotik]> password
old password: *****
New password: *****
Retype new password: *****
[Admin @ Mikrotik]]>
3. - Renaming hostname
Renaming Mikrotik Router for easy configuration, in this step
server name will be changed to "myrouter"
[Admin @ MikroTik]> system identity set name = myrouter
[Admin @ myrouter]>
4. - Setting the IP Address, Gateway, and Name Server Masqureade
- [4.1] - IP Address
Order form configuration
ip address add address = {ip address / netmask} interfaces = {interface name}
a. Provides the IP address on the interface Mikrotik. Public suppose we will use to
connection to the Internet with IP 192.168.1.2 and the Local will be used for the LAN network
us with the IP 192.168.0.30 (See topology)
[Admin @ myrouter]> ip address add address = 192.168.1.2 \
netmask = 255.255.255.0 interface = Public comment = "IP to the Internet"
[Admin @ myrouter]> ip address add address = 192.168.0.30 \
netmask = 255 255 255 224 interface = Local comment = "IP to the LAN"
b. Viewing the IP address configuration we have given
[Admin @ myrouter]> ip address print
Flags: X - disabled, I - invalid, D - dynamic
# ADDRESS NETWORK BROADCAST INTERFACE
0;;; IP Address to the Internet
192.168.0.30/27 192.168.0.0 192.168.0.31 Local
1;;; IP Address to the LAN
192.168.1.2/24 192.168.0.0 192.168.1.255 Public
[Admin @ myrouter]>
- [4.2] - Gateway
Forms Configuration Commands
ip route add gateway = {ip gateway}
a. Providing default gateway, the gateway to the internet connection is assumed is
192.168.1.1
[Admin @ myrouter]> / ip route add gateway = 192.168.1.1
b. Viewing the routing table on MikroTik Routers
[Admin @ myrouter]> ip route print
Flags: X - disabled, A - active, D - dynamic,
C - connect, S - static, r - rip, b - bgp, o - ospf
# DST-ADDRESS G GATEWAY DISTANCE INTERFACE PREFSRC
0 ADC 192.168.0.0/24 192.168.0.30 Local
1 ADC 192.168.0.0/27 192.168.1.2 Public
2 A S 0.0.0.0 / 0 r 192.168.1.1 Public
[Admin @ myrouter]>
c. Ping test to the Gateway to ensure the configuration is correct
[Admin @ myrouter]> ping 192.168.1.1
192.168.1.1 64 byte ping: ttl = 64 time <1 ms 192.168.1.1 64 byte ping: ttl = 64 time <1 ms 2 packets transmitted, 2 packets received, 0% packet loss round-trip min / avg / max = 0/0.0/0 ms [Admin @ myrouter]>
- [4.3] - NAT (Network Address Translation)
Forms Configuration Commands
ip firewall nat add chain = srcnat action = masquerade out-inteface = {ethernet
are directly connected to the Internet or Public}
a. Setup Masquerading, if Mikrotik will we use as a gateway server so that
client computer on the network can connect to the internet we need to masquerading.
[Admin @ myrouter]> ip firewall nat add chain = scrnat out-interface = Public action = masquerade
[Admin @ myrouter]>
b. Look at the configuration Masquerading
[Admin @ myrouter] ip firewall nat print
Flags: X - disabled, I - invalid, D - dynamic
0 chain = srcnat out-interface = Public action = masquerade
[Admin @ myrouter]>
- [4.4] Name servers
Forms Configuration Commands
ip dns set primary-dns = {primary} secondary-dns dns dns = {second}
a. Setup DNS on Mikrotik Routers, eg DNS with Ip Addressnya
Primary = 202.134.0.155, Secondary = 202.134.2.5
[Admin @ myrouter]> ip dns set primary-dns = 202.134.0.155 allow-remoterequests = yes
[Admin @ myrouter]> ip dns set secondary-dns = 202.134.2.5 allow-remoterequests = yes
b. Viewing the configuration control
[Admin @ myrouter]> ip dns print
primary-dns: 202.134.0.155
secondary-dns: 202.134.2.5
allow-remote-requests: no
cache-size: 2048KiB
cache-max-ttl: 1w
cache-used: 16KiB
[Admin @ myrouter]>
c. Tests for the access domain, for example with ping domain name
[Admin @ myrouter]> ping yahoo.com
216 109 112 135 64 byte ping: ttl = 48 time = 250 ms
10 packets transmitted, 10 packets received, 0% packet loss
round-trip min / avg / max = 571/571.0/571 ms
[Admin @ myrouter]>
If you have successfully reply mean DNS settings are correct.
After this step can be done to check the connection from the local network. And if
means we have successfully managed to install Mikrotik Router as a Gateway
server. After connecting with Mikrotik network can be managed using the WinBox
can be downloaded from the server mikrotik Mikrotik.com or from us. Eg Ip address server
mikrotik we 192.168.0.30, via a browser open http://192.168.0.30. In the Browser will be displayed
in a web form with multiple menus, search and download text Download WinBox from there.
Save on the local hard drive. Winbox Run, enter the IP address, username and password.
5. - DHCP Server
DHCP stands for Dynamic Host Configuration Protocol, which is a program that
allows setting the IP Address on a network performed on a centralized server,
so the PC Client does not need to configure IP Address. DHCP allows an administrator
for addressing the ip address for the client.
Form of configuration commands
ip dhcp-server setup
dhcp server interfaces = {interface used}
dhcp server space = {network that will be in dhcp}
gateway for dhcp network = {ip gateway}
address to give out ip address = {range}
dns servers = {server name}
lease time = {} of the lease granted
If we want the client get IP address automatically then we need to setup
dhcp server on the Mikrotik. Here are the steps:
a. Add the IP address pool
/ Ip pool add name = dhcp-pool ranges = 192.168.0.1-192.168.0.30
b. Add a DHCP Network and gateway that will be distributed to the client.
In this example networknya gateway is 192.168.0.0/27 and 122.168.0.30
/ Ip dhcp-server network add address = 192.168.0.0/27 gateway = 192.168.0.30 dns-server = 192.168.0.30 \
comment = ""
c. Add a DHCP server (in this example applied to the Local interface dhcp)
/ Ip dhcp-server add interface = local address-pool = dhcp-pool
d. Check the status of the DHCP server
[Admin @ myrouter]> ip dhcp-server print
Flags: X - disabled, I - invalid
# NAME INTERFACE RELAY ADDRESS-POOL LEASE-TIME ADD-ARP
Local 0dhcp1
X states that the DHCP server has not enabled it is necessary first dienablekan
previously in step e.
e. Do not Forget made first enable dhcp server
/ Ip dhcp-server enable 0
then check back to the dhcp-server such as step 4, if X has no meaning
already active
f. Tests From the client
For example:
D: \> ping www.yahoo.com
6.- Transparent Proxy Server
Proxy server is a program that can speed up access to a web
that have been accessed by another computer, because it was in the store in
caching proxy server.Transparent profitable in client management,
because system administrators do not need to setup a proxy in
each client computer's browser for the automatic redirection is performed on the
server.
Form of configuration commands:
a. Web proxy settings:
- Ip proxy set enabled = yes
port = {port that will be used}
maximal-client-connections = 1000
maximal-server-connections = 1000
- Ip proxy direct add src-address = {network that will be
NAT} action = allow
- Ip web-proxy set parent-proxy = {proxy parent / optional}
hostname = {hostname for the proxy / optional}
port = {port that will be used}
src-address = {address will be used for connection
to the parent proxy / default 0.0.0.0}
transparent-proxy = yes
max-object-size = {maximum size file to be saved
as a cache / default 4096 in Kilobytes}
max-cache-size = {maximum size hard drive that will
used as a storage cache file / unlimited
| None | 12 in megabytes}
cache-administrator = {email administrator that will be used
if a proxy error, the status will be sent
to email}
enable == yes
Sample configuration
-------
a. Web proxy settings
/ Ip web-proxy
set enabled = yes src-address = 0.0.0.0 port = 8080 \
hostname = "proxy.myrouter.com" transparent-proxy = yes \
parent-proxy = 0.0.0.0:0 cache-administrator = "support@myrouter.com" \
max-object-size = 131072KiB cache-drive = system max-cache-size = unlimited \
max-ram-cache-size = unlimited
Nat Redirect, the rule should be added to deflect REDIRECTING
HTTP traffic to the WEB-PROXY.
b. Setting for Transparant proxy firewall
Form of configuration commands:
ip firewall nat add chain = dstnat
protocol = tcp
dst-port = 80
action = redirect
to-ports = {proxy port}
The command:
---------------------------
/ Ip firewall nat
add chain = dstnat protocol = tcp dst-port = 80 action = redirect to-ports = 8080 \
comment = "" disabled = no
add chain = dstnat protocol = tcp dst-port = 3128 action = redirect to-ports = 8080 \
comment = "" disabled = no
add chain = dstnat protocol = tcp dst-port = 8000 action = redirect to-ports = 8080 \
---------------------------
above command is intended, so that all traffic to Port 80,3128,8000
deflected toward the port 8080 is a Web-Proxy port.
NOTE:
Command
/ Ip web-proxy print {to see the results of a web-proxy configuration}
/ Ip web-proxy monitor for monitoring the work {web-proxy}
7. - Bandwidth Management
QoS plays an important role in terms of providing services good on the client. For that we need the bandwidth management for each data set is passed, so the division of bandwidth into fair. In this case also includes a packet RouterOS software for memanagement bandwidth.
Form of configuration commands:
queue simple add name = {name}
target-addresses = {ip address of the destination}
interfaces = {interface used to pass data}
max-limit = {out / in}
Below there is a configuration of traffic shaping or bandwidth management with Simple Queue method, as the name implies, this type of queue is simple, but has a weakness, sometimes leak bandwidth or bandwidth is not real in the monitor. Usage for 10 clients, Queue type is not a problem.
Client is assumed there are as many as 15 clients, and each client was given ration of 8kbps minimum bandwidth, and a maximum of 48kbps. Whereas Total bandwidth of 192Kbps. For the upstream is not given a rule, means each client can use the bandwidth uptream maximum. Note the priority command, the range of priority in Mikrotik eight. Means from 1 to 8, priority 1 is highest priority, while priority 8 is the lowest priority.
The following example kongirufasinya.
---------------------------
/ Queue simple
add name = "trafikshaping" target-addresses = 192.168.0.0/27 dst-address = 0.0.0.0 / 0 \
interface = all parent = none priority = 1 queue = default / default \

The command above because in the form of the command line, can also copy paste, then paste it into the consol mikrotiknya. remember see first path or active directory. Please dipaste course, if the position
direktorynya in Root.
-----------------------
Terminal vt102 detected, using multiline input mode
[Admin @ MikroTik]>
----------------------
Another option is the method of bandwidth management, if if wanted bandwidth is shared equally by Mikrotik, such as bandwidth 256kbps downstream and 256kbps upstream. While the client will
access as many as 10 clients, each client automatically gets a small upstream and downstream bandwidth of 256kbps divided by 10. So each one can be 25.6 kbps. If only 2 Client who access it each can be 128kbps.
For that type used PCQ (Per Connection Queue), which can be automatically divide the traffic per client. About the type of queue in mikrotik This can be read on the manual in http://www.mikrotik.com/testdocs/
ros/2.9/root/queue.php.
Previously need to be made a rule in the mangle. Such as:
-----------------------
/ Ip firewall mangle add chain = forward src-address = 192.168.0.0/27 \
action = mark-connection new-connection-mark = users-con
/ Ip firewall mangle add connection-mark = users-con action = mark-packet \
new-packet-mark = users chain = forward
------------------------
Because type PCQ does not exist, then it needs to be added, there are two types of this PCQ. First named pcq-download, which will regulate all traffic through the destination address / destination address. Traffic is passing Local interface. So that all traffic download / downstream coming from the network 192.168.0.0/27 will be shared automatically.
PCQ second type, called pcq-upload, to regulate all upstream traffic derived from the source address / source address. Traffic is passing public interface. So that all traffic upload / upstream originating from the network 192.168.0.0/27 will be shared automatically.
Command:
-------------------------
/ Queue type add name = pcq-download kind = pcq pcq-classifier = dst-address
/ Queue type add name = pcq-upload kind = pcq pcq-classifier = src-address
-------------------------
Once the rules for the PCQ and Mangle added, now for the rules traffic division. Queue Queue Tree is used, ie:
-------------------------
/ Queue tree add parent = Local queue = pcq-download packet-mark = users
/ Queue tree add parent = Public queue = pcq-upload packet-mark = users
-------------------------
The command above assumes that if the bandwidth received from the provider Internet berflukstuasi or changing. If we believe that the bandwidth received, for example can 256kbs downstream, and 256kbps upstream, then No more rules, such as:
For downstream traffic:
------------------------
/ Queue tree add name = Download parent = Local max-limit = 256k
/ Queue tree add parent = Download queue = pcq-download packet-mark = users
-------------------------
And upstream traffic:
-------------------------
/ Queue tree add name = Upload parent = Public max-limit = 256k
/ Queue tree add parent = Upload queue = pcq-upload packet-mark = users
-------------------------
8. - MRTG Monitor via Web
This facility is necessary for monitoring traffic in the form of graphs, can viewed using a browser. MRTG (The Multi Router Traffic Grapher) has dibuild such a way that allows us to use it. Already available packaged basically.
Example configuration
-------------------------
/ Tool graphing
set store-every = 5min
/ Tool graphing interface
add interface = all allow-address = 0.0.0.0 / 0 store-on-disk = yes disabled = no
-------------------------
The above command will display a graph of the traffic that passes through the interface good network of Public Interface and Local Interface, which rendered every 5 minutes. Addresses can also be set anything that can access MRTG is, the allow-address parameter.
9. - Security in Mikrotik
After some configuration above has been prepared, of course not forgetting our consider the security of this mikrotik gateway machine, there are few facilities used. In this case will be discussed on the firewall. Facilities
The underlying this firewall is similar to IP TABLES on Gnu / Linux only some commands have been simplified but efficient.
In Mikrotik firewall command is contained in IP mode, ie
[Admin @ myrouter]> / ip firewall
There are several packet filters like mangle, nat, and filters.
-------------------------
[Admin @ myrouter] ip firewall>?
Firewall allows IP packet filtering on per packet basis.
.. - Go up to the ip
mangle / - The packet marking management
nat / - Network Address Translation
connection / - Active Connections
filter / - Firewall filters
address-list / -
service-port / - Service port management
export -
-------------------------
For this time we will see the ip firewall filter configuration.
Because the breadth of the firewall filter parameters for the discussion of Firewall Filters can be seen in the manual mikrotik, in http://www.mikrotik.com/testdocs/ros/2.9/ip/filter.php
Configuration below can block some of the Trojan, Virus, Backdoor which have been identified previously used either Port Numbers and Protocols. It has also been configured to withstand the flooding of the Network and Public Local network. As well as providing rules for access control in order, Range only certain tissues that can perform remote or access the service Mikrotik specific to our machine.

- [10/01] - Service and Viewing the Active Service with PortScanner
To ensure that any active service in Machine mikrotik, we need to scan to a specific port, if there are services that are not needed, better off alone.
To disable and enable servise, the command is:
We verify what services are active
----------------------------
[Admin @ myrouter]> ip service
[Admin @ myrouter] ip service> print
Flags: X - disabled, I - invalid
# NAME PORT ADDRESS CERTIFICATE
X 0 telnet 23 0.0.0.0 / 0
1 ftp 21 0.0.0.0 / 0
2 www 80 0.0.0.0 / 0
3 ssh 22 0.0.0.0 / 0
4 www-ssl 443 0.0.0.0 / 0 none
[Admin @ myrouter]ip service>
----------------------------
Suppose the FTP service is disabled, ie in the above list is located at
number 1 (see Flags) then:
---------------------------
[Admin @ myrouter] ip service> set 1 disabled = yes
---------------------------
We need to check again,
---------------------------
[Admin @ myrouter] ip service> print
Flags: X - disabled, I - invalid
# NAME PORT ADDRESS CERTIFICATE
X 0 telnet 23 0.0.0.0 / 0
1 X ftp 21 0.0.0.0 / 0
2 www 80 0.0.0.0 / 0
3 ssh 22 0.0.0.0 / 0
4 www-ssl 443 0.0.0.0 / 0 none
[Admin@myrouter] ip service>
---------------------------
Now the FTP service has been disabled.
Using nmap tool we can check what ports are active on the machine
gateway has been configured.

From the results of such scanning can we take the conclusion, that the service and active port is a FTP version of the MikroTik router ftpd 2.9.27. To SSH with OpenSSH version 2.3.0 mikrotik 2.9.27 (protocol 1.99). And the Web use the Squid proxy in Squid version webproxy 2.5.STABLE11.
Of course, the vendor has to patch against mikrotik Hole or Vulnerabilities of the above Protocol Version.
- [10/02] - Network Administration Tool
Practically speaking, there are some tools that can be utilized in mela do network troubleshooting, such as tools ping, traceroute, ssh, etc.. Some tools are often used later in the day-to-day administration
are:
o Telnet
o SSH
o Traceroute
o Sniffer
a. Telnet
Remote commands are almost the same machine with the use of the existing telnet
on Linux or Windows.
[Admin @myrouter]> system telnet?
Sekilias above command to see what parameters are there. For example
remote machine with IP address 192.168.0.21 and port 23. Then
[Admin @ myrouter]> system telnet 192.168.0.21
Use of telnet should be limited to certain conditions for reasons security, as we know, a packet of data sent via telnet has not been encrypted. To be more safe we use SSH.
b. SSH
Together with the telnet command is also needed in the remote machine, and principle same parameters with the command on Linux and Windows.
[Admin @myrouter]> system ssh 192.168.0.21
SSH parameters above, a slight difference with telnet. If you see helpnya
has an additional parameter of the user.
--------------------------
[Admin @ myrouter]> ssh system?
The SSH feature can be used with Various SSH Telnet clients to securely connect
to and administrate the router
-
user - User name
port - Port number
[Admin @ myrouter]>
--------------------------
Suppose we are going to be remotely on a machine with the system
Linux operation, which has the account, username and password Root
123 456 in the address 66.213.7.30. Then the command,
--------------------------
[Admin @ myrouter]> system 66.213.7.30 ssh user = root
root@66.213.7.30 's password:
--------------------------
c. Traceroute
Knowing what or router hops through which a packet until the packet
was sent to the destination, we usually use the traceroute. With this tool
can be routed anywhere in the analysis of the course packet.
Suppose want to know the path the packet to the server yahoo, then:
--------------------------
[Admin @ myrouter]> tool traceroute yahoo.com ADDRESS STATUS
1 63.219.6.nnn 00:00:00 00:00:00 00:00:00
2 222.124.4.nnn 00:00:00 00:00:00 00:00:00

14 216 109 112 135 0:00:00 timeout timeout
--------------------------
d. Sniffer
We can capture and packet-packet tap running in our network, this tool has been provided by Mikrotik useful in analyzing the traffic.
--------------------------
[Admin @ myrouter]> sniffer tool
Packet sniffering
.. - Go up to tool
start - Start / reset sniffering
stop - Stop sniffering
save - Save currently sniffed packets
packet / - sniffed packets management
protocol / - Protocol management
host / - Host management
connection / - Connection management
print -
get - get value of property
set -
edit - edit the value of property
export -
--------------------------
To begin the process of sniffing can use the Start command, while
stop it can make use of the Stop command.
[Admin @ myrouter]> start sniffer tool
Let us continue with the introduction of this command. Once logged in, check the condition of the interface or ethernet card.
1. Looking at the condition of the interface on Router Mikrotik
[Admin @ MikroTik]> interface print
Flags: X - disabled, D - dynamic, R - running
# NAME TYPE RX-RATE TX-RATE MTU
0 R ether1 ether 0 0 1500
1 R ether2 ether 0 0 1500
[Admin @ MikroTik]>
If there is an X interface (disabled) after the number (0.1), then check again etherned card, should be R (running).
a. Renaming interface
[Admin @ MikroTik]> interface (enter)
b. To rename a Public Interface ether1 (or whatever his name), then
[Admin @ MikroTik] interface> set 0 name = Public
c. Likewise for ether2, say his name changed to Local, then
[Admin @ MikroTik] interface> set 1 name = Local
d. or just from the position of the root directory, use the sign "/", without quotes
[Admin @ MikroTik]> / interface set 0 name = Public
e. Check again if the interface name had been changed.
[Admin @ MikroTik]> / interface print
Flags: X - disabled, D - dynamic, R - running
# NAME TYPE RX-RATE TX-RATE MTU
0 R Local ether 0 0 1500
1 R Public ether 0 0 1500
2. - Change the default password
To change the default password security
[Admin @ Mikrotik]> password
old password: *****
New password: *****
Retype new password: *****
[Admin @ Mikrotik]]>
3. - Renaming hostname
Renaming Mikrotik Router for easy configuration, in this step
server name will be changed to "myrouter"
[Admin @ MikroTik]> system identity set name = myrouter
[Admin @ myrouter]>
4. - Setting the IP Address, Gateway, and Name Server Masqureade
- [4.1] - IP Address
Order form configuration
ip address add address = {ip address / netmask} interfaces = {interface name}
a. Provides the IP address on the interface Mikrotik. Public suppose we will use to
connection to the Internet with IP 192.168.1.2 and the Local will be used for the LAN network
us with the IP 192.168.0.30 (See topology)
[Admin @ myrouter]> ip address add address = 192.168.1.2 \
netmask = 255.255.255.0 interface = Public comment = "IP to the Internet"
[Admin @ myrouter]> ip address add address = 192.168.0.30 \
netmask = 255 255 255 224 interface = Local comment = "IP to the LAN"
b. Viewing the IP address configuration we have given
[Admin @ myrouter]> ip address print
Flags: X - disabled, I - invalid, D - dynamic
# ADDRESS NETWORK BROADCAST INTERFACE
0;;; IP Address to the Internet
192.168.0.30/27 192.168.0.0 192.168.0.31 Local
1;;; IP Address to the LAN
192.168.1.2/24 192.168.0.0 192.168.1.255 Public
[Admin @ myrouter]>
- [4.2] - Gateway
Forms Configuration Commands
ip route add gateway = {ip gateway}
a. Providing default gateway, the gateway to the internet connection is assumed is
192.168.1.1
[Admin @ myrouter]> / ip route add gateway = 192.168.1.1
b. Viewing the routing table on MikroTik Routers
[Admin @ myrouter]> ip route print
Flags: X - disabled, A - active, D - dynamic,
C - connect, S - static, r - rip, b - bgp, o - ospf
# DST-ADDRESS G GATEWAY DISTANCE INTERFACE PREFSRC
0 ADC 192.168.0.0/24 192.168.0.30 Local
1 ADC 192.168.0.0/27 192.168.1.2 Public
2 A S 0.0.0.0 / 0 r 192.168.1.1 Public
[Admin @ myrouter]>
c. Ping test to the Gateway to ensure the configuration is correct
[Admin @ myrouter]> ping 192.168.1.1
192.168.1.1 64 byte ping: ttl = 64 time <1 ms 192.168.1.1 64 byte ping: ttl = 64 time <1 ms 2 packets transmitted, 2 packets received, 0% packet loss round-trip min / avg / max = 0/0.0/0 ms [Admin @ myrouter]>
- [4.3] - NAT (Network Address Translation)
Forms Configuration Commands
ip firewall nat add chain = srcnat action = masquerade out-inteface = {ethernet
are directly connected to the Internet or Public}
a. Setup Masquerading, if Mikrotik will we use as a gateway server so that
client computer on the network can connect to the internet we need to masquerading.
[Admin @ myrouter]> ip firewall nat add chain = scrnat out-interface = Public action = masquerade
[Admin @ myrouter]>
b. Look at the configuration Masquerading
[Admin @ myrouter] ip firewall nat print
Flags: X - disabled, I - invalid, D - dynamic
0 chain = srcnat out-interface = Public action = masquerade
[Admin @ myrouter]>
- [4.4] Name servers
Forms Configuration Commands
ip dns set primary-dns = {primary} secondary-dns dns dns = {second}
a. Setup DNS on Mikrotik Routers, eg DNS with Ip Addressnya
Primary = 202.134.0.155, Secondary = 202.134.2.5
[Admin @ myrouter]> ip dns set primary-dns = 202.134.0.155 allow-remoterequests = yes
[Admin @ myrouter]> ip dns set secondary-dns = 202.134.2.5 allow-remoterequests = yes
b. Viewing the configuration control
[Admin @ myrouter]> ip dns print
primary-dns: 202.134.0.155
secondary-dns: 202.134.2.5
allow-remote-requests: no
cache-size: 2048KiB
cache-max-ttl: 1w
cache-used: 16KiB
[Admin @ myrouter]>
c. Tests for the access domain, for example with ping domain name
[Admin @ myrouter]> ping yahoo.com
216 109 112 135 64 byte ping: ttl = 48 time = 250 ms
10 packets transmitted, 10 packets received, 0% packet loss
round-trip min / avg / max = 571/571.0/571 ms
[Admin @ myrouter]>
If you have successfully reply mean DNS settings are correct.
After this step can be done to check the connection from the local network. And if
means we have successfully managed to install Mikrotik Router as a Gateway
server. After connecting with Mikrotik network can be managed using the WinBox
can be downloaded from the server mikrotik Mikrotik.com or from us. Eg Ip address server
mikrotik we 192.168.0.30, via a browser open http://192.168.0.30. In the Browser will be displayed
in a web form with multiple menus, search and download text Download WinBox from there.
Save on the local hard drive. Winbox Run, enter the IP address, username and password.
5. - DHCP Server
DHCP stands for Dynamic Host Configuration Protocol, which is a program that
allows setting the IP Address on a network performed on a centralized server,
so the PC Client does not need to configure IP Address. DHCP allows an administrator
for addressing the ip address for the client.
Form of configuration commands
ip dhcp-server setup
dhcp server interfaces = {interface used}
dhcp server space = {network that will be in dhcp}
gateway for dhcp network = {ip gateway}
address to give out ip address = {range}
dns servers = {server name}
lease time = {} of the lease granted
If we want the client get IP address automatically then we need to setup
dhcp server on the Mikrotik. Here are the steps:
a. Add the IP address pool
/ Ip pool add name = dhcp-pool ranges = 192.168.0.1-192.168.0.30
b. Add a DHCP Network and gateway that will be distributed to the client.
In this example networknya gateway is 192.168.0.0/27 and 122.168.0.30
/ Ip dhcp-server network add address = 192.168.0.0/27 gateway = 192.168.0.30 dns-server = 192.168.0.30 \
comment = ""
c. Add a DHCP server (in this example applied to the Local interface dhcp)
/ Ip dhcp-server add interface = local address-pool = dhcp-pool
d. Check the status of the DHCP server
[Admin @ myrouter]> ip dhcp-server print
Flags: X - disabled, I - invalid
# NAME INTERFACE RELAY ADDRESS-POOL LEASE-TIME ADD-ARP
Local 0dhcp1
X states that the DHCP server has not enabled it is necessary first dienablekan
previously in step e.
e. Do not Forget made first enable dhcp server
/ Ip dhcp-server enable 0
then check back to the dhcp-server such as step 4, if X has no meaning
already active
f. Tests From the client
For example:
D: \> ping www.yahoo.com
6.- Transparent Proxy Server
Proxy server is a program that can speed up access to a web
that have been accessed by another computer, because it was in the store in
caching proxy server.Transparent profitable in client management,
because system administrators do not need to setup a proxy in
each client computer's browser for the automatic redirection is performed on the
server.
Form of configuration commands:
a. Web proxy settings:
- Ip proxy set enabled = yes
port = {port that will be used}
maximal-client-connections = 1000
maximal-server-connections = 1000
- Ip proxy direct add src-address = {network that will be
NAT} action = allow
- Ip web-proxy set parent-proxy = {proxy parent / optional}
hostname = {hostname for the proxy / optional}
port = {port that will be used}
src-address = {address will be used for connection
to the parent proxy / default 0.0.0.0}
transparent-proxy = yes
max-object-size = {maximum size file to be saved
as a cache / default 4096 in Kilobytes}
max-cache-size = {maximum size hard drive that will
used as a storage cache file / unlimited
| None | 12 in megabytes}
cache-administrator = {email administrator that will be used
if a proxy error, the status will be sent
to email}
enable == yes
Sample configuration
-------
a. Web proxy settings
/ Ip web-proxy
set enabled = yes src-address = 0.0.0.0 port = 8080 \
hostname = "proxy.myrouter.com" transparent-proxy = yes \
parent-proxy = 0.0.0.0:0 cache-administrator = "support@myrouter.com" \
max-object-size = 131072KiB cache-drive = system max-cache-size = unlimited \
max-ram-cache-size = unlimited
Nat Redirect, the rule should be added to deflect REDIRECTING
HTTP traffic to the WEB-PROXY.
b. Setting for Transparant proxy firewall
Form of configuration commands:
ip firewall nat add chain = dstnat
protocol = tcp
dst-port = 80
action = redirect
to-ports = {proxy port}
The command:
---------------------------
/ Ip firewall nat
add chain = dstnat protocol = tcp dst-port = 80 action = redirect to-ports = 8080 \
comment = "" disabled = no
add chain = dstnat protocol = tcp dst-port = 3128 action = redirect to-ports = 8080 \
comment = "" disabled = no
add chain = dstnat protocol = tcp dst-port = 8000 action = redirect to-ports = 8080 \
---------------------------
above command is intended, so that all traffic to Port 80,3128,8000
deflected toward the port 8080 is a Web-Proxy port.
NOTE:
Command
/ Ip web-proxy print {to see the results of a web-proxy configuration}
/ Ip web-proxy monitor for monitoring the work {web-proxy}
7. - Bandwidth Management
QoS plays an important role in terms of providing services good on the client. For that we need the bandwidth management for each data set is passed, so the division of bandwidth into fair. In this case also includes a packet RouterOS software for memanagement bandwidth.
Form of configuration commands:
queue simple add name = {name}
target-addresses = {ip address of the destination}
interfaces = {interface used to pass data}
max-limit = {out / in}
Below there is a configuration of traffic shaping or bandwidth management with Simple Queue method, as the name implies, this type of queue is simple, but has a weakness, sometimes leak bandwidth or bandwidth is not real in the monitor. Usage for 10 clients, Queue type is not a problem.
Client is assumed there are as many as 15 clients, and each client was given ration of 8kbps minimum bandwidth, and a maximum of 48kbps. Whereas Total bandwidth of 192Kbps. For the upstream is not given a rule, means each client can use the bandwidth uptream maximum. Note the priority command, the range of priority in Mikrotik eight. Means from 1 to 8, priority 1 is highest priority, while priority 8 is the lowest priority.
The following example kongirufasinya.
---------------------------

The command above because in the form of the command line, can also copy paste, then paste it into the consol mikrotiknya. remember see first path or active directory. Please dipaste course, if the position
direktorynya in Root.
-----------------------
Terminal vt102 detected, using multiline input mode
[Admin @ MikroTik]>
----------------------
Another option is the method of bandwidth management, if if wanted bandwidth is shared equally by Mikrotik, such as bandwidth 256kbps downstream and 256kbps upstream. While the client will
access as many as 10 clients, each client automatically gets a small upstream and downstream bandwidth of 256kbps divided by 10. So each one can be 25.6 kbps. If only 2 Client who access it each can be 128kbps.
For that type used PCQ (Per Connection Queue), which can be automatically divide the traffic per client. About the type of queue in mikrotik This can be read on the manual in http://www.mikrotik.com/testdocs/
ros/2.9/root/queue.php.
Previously need to be made a rule in the mangle. Such as:
-----------------------
/ Ip firewall mangle add chain = forward src-address = 192.168.0.0/27 \
action = mark-connection new-connection-mark = users-con
/ Ip firewall mangle add connection-mark = users-con action = mark-packet \
new-packet-mark = users chain = forward
------------------------
Because type PCQ does not exist, then it needs to be added, there are two types of this PCQ. First named pcq-download, which will regulate all traffic through the destination address / destination address. Traffic is passing Local interface. So that all traffic download / downstream coming from the network 192.168.0.0/27 will be shared automatically.
PCQ second type, called pcq-upload, to regulate all upstream traffic derived from the source address / source address. Traffic is passing public interface. So that all traffic upload / upstream originating from the network 192.168.0.0/27 will be shared automatically.
Command:
-------------------------
/ Queue type add name = pcq-download kind = pcq pcq-classifier = dst-address
/ Queue type add name = pcq-upload kind = pcq pcq-classifier = src-address
-------------------------
Once the rules for the PCQ and Mangle added, now for the rules traffic division. Queue Queue Tree is used, ie:
-------------------------
/ Queue tree add parent = Local queue = pcq-download packet-mark = users
/ Queue tree add parent = Public queue = pcq-upload packet-mark = users
-------------------------
The command above assumes that if the bandwidth received from the provider Internet berflukstuasi or changing. If we believe that the bandwidth received, for example can 256kbs downstream, and 256kbps upstream, then No more rules, such as:
For downstream traffic:
------------------------
/ Queue tree add name = Download parent = Local max-limit = 256k
/ Queue tree add parent = Download queue = pcq-download packet-mark = users
-------------------------
And upstream traffic:
-------------------------
/ Queue tree add name = Upload parent = Public max-limit = 256k
/ Queue tree add parent = Upload queue = pcq-upload packet-mark = users
-------------------------
8. - MRTG Monitor via Web
This facility is necessary for monitoring traffic in the form of graphs, can viewed using a browser. MRTG (The Multi Router Traffic Grapher) has dibuild such a way that allows us to use it. Already available packaged basically.
Example configuration
-------------------------
/ Tool graphing
set store-every = 5min
/ Tool graphing interface
add interface = all allow-address = 0.0.0.0 / 0 store-on-disk = yes disabled = no
-------------------------
The above command will display a graph of the traffic that passes through the interface good network of Public Interface and Local Interface, which rendered every 5 minutes. Addresses can also be set anything that can access MRTG is, the allow-address parameter.
9. - Security in Mikrotik
After some configuration above has been prepared, of course not forgetting our consider the security of this mikrotik gateway machine, there are few facilities used. In this case will be discussed on the firewall. Facilities
The underlying this firewall is similar to IP TABLES on Gnu / Linux only some commands have been simplified but efficient.
In Mikrotik firewall command is contained in IP mode, ie
[Admin @ myrouter]> / ip firewall
There are several packet filters like mangle, nat, and filters.
-------------------------
[Admin @ myrouter] ip firewall>?
Firewall allows IP packet filtering on per packet basis.
.. - Go up to the ip
mangle / - The packet marking management
nat / - Network Address Translation
connection / - Active Connections
filter / - Firewall filters
address-list / -
service-port / - Service port management
export -
-------------------------
For this time we will see the ip firewall filter configuration.
Because the breadth of the firewall filter parameters for the discussion of Firewall Filters can be seen in the manual mikrotik, in http://www.mikrotik.com/testdocs/ros/2.9/ip/filter.php
Configuration below can block some of the Trojan, Virus, Backdoor which have been identified previously used either Port Numbers and Protocols. It has also been configured to withstand the flooding of the Network and Public Local network. As well as providing rules for access control in order, Range only certain tissues that can perform remote or access the service Mikrotik specific to our machine.

- [10/01] - Service and Viewing the Active Service with PortScanner
To ensure that any active service in Machine mikrotik, we need to scan to a specific port, if there are services that are not needed, better off alone.
To disable and enable servise, the command is:
We verify what services are active
----------------------------
[Admin @ myrouter]> ip service
[Admin @ myrouter] ip service> print
Flags: X - disabled, I - invalid
# NAME PORT ADDRESS CERTIFICATE
X 0 telnet 23 0.0.0.0 / 0
1 ftp 21 0.0.0.0 / 0
2 www 80 0.0.0.0 / 0
3 ssh 22 0.0.0.0 / 0
4 www-ssl 443 0.0.0.0 / 0 none
[Admin @ myrouter]ip service>
----------------------------
Suppose the FTP service is disabled, ie in the above list is located at
number 1 (see Flags) then:
---------------------------
[Admin @ myrouter] ip service> set 1 disabled = yes
---------------------------
We need to check again,
---------------------------
[Admin @ myrouter] ip service> print
Flags: X - disabled, I - invalid
# NAME PORT ADDRESS CERTIFICATE
X 0 telnet 23 0.0.0.0 / 0
1 X ftp 21 0.0.0.0 / 0
2 www 80 0.0.0.0 / 0
3 ssh 22 0.0.0.0 / 0
4 www-ssl 443 0.0.0.0 / 0 none
[Admin@myrouter] ip service>
---------------------------
Now the FTP service has been disabled.
Using nmap tool we can check what ports are active on the machine
gateway has been configured.

-------------------------
From the results of such scanning can we take the conclusion, that the service and active port is a FTP version of the MikroTik router ftpd 2.9.27. To SSH with OpenSSH version 2.3.0 mikrotik 2.9.27 (protocol 1.99). And the Web use the Squid proxy in Squid version webproxy 2.5.STABLE11.
Of course, the vendor has to patch against mikrotik Hole or Vulnerabilities of the above Protocol Version.
- [10/02] - Network Administration Tool
Practically speaking, there are some tools that can be utilized in mela do network troubleshooting, such as tools ping, traceroute, ssh, etc.. Some tools are often used later in the day-to-day administration
are:
o Telnet
o SSH
o Traceroute
o Sniffer
a. Telnet
Remote commands are almost the same machine with the use of the existing telnet
on Linux or Windows.
[Admin @myrouter]> system telnet?
Sekilias above command to see what parameters are there. For example
remote machine with IP address 192.168.0.21 and port 23. Then
[Admin @ myrouter]> system telnet 192.168.0.21
Use of telnet should be limited to certain conditions for reasons security, as we know, a packet of data sent via telnet has not been encrypted. To be more safe we use SSH.
b. SSH
Together with the telnet command is also needed in the remote machine, and principle same parameters with the command on Linux and Windows.
[Admin @myrouter]> system ssh 192.168.0.21
SSH parameters above, a slight difference with telnet. If you see helpnya
has an additional parameter of the user.
--------------------------
[Admin @ myrouter]> ssh system?
The SSH feature can be used with Various SSH Telnet clients to securely connect
to and administrate the router
-
user - User name
port - Port number
[Admin @ myrouter]>
--------------------------
Suppose we are going to be remotely on a machine with the system
Linux operation, which has the account, username and password Root
123 456 in the address 66.213.7.30. Then the command,
--------------------------
[Admin @ myrouter]> system 66.213.7.30 ssh user = root
root@66.213.7.30 's password:
--------------------------
c. Traceroute
Knowing what or router hops through which a packet until the packet
was sent to the destination, we usually use the traceroute. With this tool
can be routed anywhere in the analysis of the course packet.
Suppose want to know the path the packet to the server yahoo, then:
--------------------------
[Admin @ myrouter]> tool traceroute yahoo.com ADDRESS STATUS
1 63.219.6.nnn 00:00:00 00:00:00 00:00:00
2 222.124.4.nnn 00:00:00 00:00:00 00:00:00
3 192.168.34.41 00:00:00 00:00:00 00:00:00
4 61.94.1.253 00:00:00 00:00:00 00:00:00
5 203,208,143,173 00:00:00 00:00:00 00:00:00
6 203.208.182.5 00:00:00 00:00:00 00:00:00
7 203,208,182,114 00:00:00 00:00:00 00:00:00
8 203,208,168,118 00:00:00 00:00:00 00:00:00
9 203 208 168 134 timeout 00:00:00 00:00:00
Timeout timeout 10 00:00:00 216.115.101.34
11 216 115 101 129 0:00:00 timeout timeout
12 216.115.108.1 timeout timeout 00:00:00
13 216,109,120,249 00:00:00 00:00:00 00:00:00
14 216 109 112 135 0:00:00 timeout timeout
--------------------------
d. Sniffer
We can capture and packet-packet tap running in our network, this tool has been provided by Mikrotik useful in analyzing the traffic.
--------------------------
[Admin @ myrouter]> sniffer tool
Packet sniffering
.. - Go up to tool
start - Start / reset sniffering
stop - Stop sniffering
save - Save currently sniffed packets
packet / - sniffed packets management
protocol / - Protocol management
host / - Host management
connection / - Connection management
print -
get - get value of property
set -
edit - edit the value of property
export -
--------------------------
To begin the process of sniffing can use the Start command, while
stop it can make use of the Stop command.
[Admin @ myrouter]> start sniffer tool
