How do you force UT3 to use the second NIC

[gorrister]

I have two network cards in my pc and need to use the second one for the game how di I force it to use the second card?

I think you'll have to disable the other one entirely.

You can have at most one logical internet gateway at once on your PC, and it can't be another configuration for a specific game.
You do not have to disable any NIC, e.g. if you use that PC as a router, but you also cannot choose the network interface for the internet connection in the fly.

What's the problem actually?
