Ok, im going to try to explain this as thoroughly as possible.

We have cable ISP. we have an ISA 2004 server. One nic on ISA goes to the cable modem, one goes to a switch on the LAN. This setup has worked flawlessly for over 2 years. Recently we have had an issue where we lose internet connectivity. DNS still works, its just HTTP traffic. I thought maybe it was a bad NIC, and this particular server has 2 dual nics in it. I changed from 1 to the other, and suddenly only computers on my 192.168.1.x subnet can get online. i have 2 others, 192.168.2.x and 3.x those two cannot get online, but can still route other traffic, its just internet traffic that is down. So my question, what configuration changed have to be made when changing out a nic? I entered the correct IP information for both internal and external.
