Trouble connecting WXP in W2K network

I have a small network of four W2K computers. One is a W2k server. I want to add a WXP Home computer. This computer is used for DSL. I added a second network card for the LAN. When I went to My Network Places, I found both cards and a "network bridge". I right clicked, went to properties, and chose TCP/IP to type the static address of my LAN. Whenever I type the IP address on one connection, it appears on BOTH connections! Of course, if I leave like that, I won't be able to use my DSL, because the DSL card is configured for DHCP. If I take off the IP address from one card, both cards are now dynamically configured. How do I make it so that one card has my LAN settings, and the other card stays dinamically connected?
