Cable setup
Basic Cable Internet Setup
First we will configure interface that is connected to WAN.
/ ip address add address=192.168.1.20/24 network=192.168.1.0 broadcast=192.168.1.255 interface=ether2
Now one interface is configured and connected to WAN (with ip 192.168.1.20/24). Now we will configure second interface for our Local Network.
/ ip address add address=192.168.0.1/24 network=192.168.0.0 broadcast=192.168.0.255 interface=ether1
Now we will configure DHCP using WinBOX, download Winbox from http://www.mikrotik.com and login to you MT Router. Then goto IP > DHCP-Server, now press Setup Button, then you will see a similar window as shown below. Just select the interface that you have configured for your Local Network (as in our example it is ether1), now just press Next till the end of setup.
Now we will configure DNS for our local network. Goto IP > DNS, press Settings button then add you Primary and Secondary DNS Server IP as provided by your Internet Service Provider. Also make sure that you select "Allow Remote Requests", so that you can give your MT Router's IP as a DNS Server to your Clients.
