I have Ubuntu 12.04 installed on my system to use as a server in my office having 50 employees. I have 2 LAN cards in my system:
- One for input from a BSNL router (192.168.1.250) to my Ubuntu server (192.168.1.1.)
- Another one from the server (192.168.1.1) to a switch which connects all the employees through squid from that switch via LAN cables.
How can I configure both LAN cards and squid, as I wants to block some sites and make some restriction on the network.
