Problems in internet sharing?

I have a wired network, consisting of 3 computers. On one of my comps i have 2 lan cards, of which one is connected to the internet and the other to the network. My anti virus software is trend micro. If the antivirus software is switched off the internet can be accessed from any comp. But when i switch it on i cannot access the net. File access is not a problem. The funny thing is my internet login page (Asianet) is accessible if i type the address ie (http://10.129.0.13/24online/webpages/cli... in the address bar. I have tried to configure the network setting of both the anti virus and the lan card but to no avail. Please help

you have to enable routing :

you need to configure each NIC with the appropriate IP address for the segments that it's connected to.

Next, you need to configure that IP as the Default Gateway for all the computers on that NIC.

Say, if you have 2 segments (we'll call them Segment A and Segment B respectively) with the following Network IDs:

Segment A - 192.168.0.0/24

Segment B - 192.168.1.0/24

and on your computer you have 2 NICs (we'll call them NIC A and NIC B respectively) with the following IP addresses:

NIC A - 192.168.0.1

NIC B - 192.168.1.1

Then the IP addresses of NIC A and NIC B will be the Default Gateways for segment A and B respectively.
