Hi

I have a web filtering gateway server with 2 network card in. Card 1 goes to the router and card 2 goes to the desktops and the gateway filters internet traffic passing through it.

This has always worked fine until I changed to a 2820n router. Now card 2 always shows a red light and no connection.

I have tried another network card and a 2820 router but still get the same problem.

If I use a Netgear it works fine.

Is there a setting in the 2820 that could be causing this problem?
