Mikrotik as Gateway

Note: This is not the best tutorial on Mikrotik, but it is one of easiest tutorial to configure Mikrotik as gateway 🙂


In this scenario, Mikrotik will work as dhcp, dns, and default gateway for local network.

Local Network :

Public: (In this scenario)

I assume that you already install the fresh copy of mikrotik  on any low end (P III, P IV or whatever) machine. Default username is “admin” and there is no password , by default.

Login to the Mikrotik router:

After login, you will see the screen something like this:

After login, first thing we need to do is to change password:


Check the interface(s) Setting by using this command:

interface print

Change the interface(s )name by using these commands:

interface set 0 name=WAN
interface set 1 name=LAN

Now, check the interface(s) again:

interface print

Assign the ip address to LAN interface:

ip address add address= interface=LAN

Assign the ip address to WAN interface:

ip address add address= interface=WAN

Now, check the ip address setting:

ip address print

Add the default route using this command:

ip route add gateway=

Check the routing table:

ip route print

DNS setup on Mikrotik:

ip dns set primary-dns= secondary-dns=
ip dns set allow-remote-requests=yes 

DNS settings check:

ip dns print

DHCP Configuration:

ip dhcp-server setup

Configuration of NAT on Mikrotik:

ip firewall nat add chain=srcnat action=masquerade out-interface=WAN

Testing from one of the Local Network’s Client:

Hope this will help you!

Please Remember me in your prayers!
