I have 2 IPs leased from my cable company. One is used for my gaming computer, while the other goes to a wireless router that services the rest of the house. I'd like to be able to have my gaming computer access the rest of the network, but I've had some weird connection drops when I'm connected to my modem and my wireless router at the same time, as they both go out to the internet.

If I bridge the NIC that uses the modem, and the NIC that connects to the wireless network, how do I ensure that my original leased IP is what internet applications see, and the wireless router's leased IP is not? I don't really know all that much about how XP routes things.

Basically I want to use stuff like WinVNC from the wireless network, to access my computer, and transfer files. I don't want to go through the router to access the 'net though.
 
Do you have a default gateway configured for each NIC? If so, then that may be your problem. You should only have one default gateway for your computer. In your case the NIC with IP address from you cable company should have a default gateway and the other NIC should not.
 
Buy SMC7004VBR Router (about $50).

This Router can put up to 10 computers in the DMZ provided you have independent external IPs (which you have).

Use your current Wireless Router as a switch with an Access Point.

Plug your Game computer to the Router like the rest of the Computers. The Router will give the Game Computer a LAN IP and will ?Bridge? it to the second external IP that you are using now.

How do I use a Wireless Cable/DSL Router as a Switch with an Access Point?
 
I have that router, and the DMZ doesn't function as well as I'd hoped.
EDIT: Didn't try it with specific IPs, however. I'll have to look at that later.
 
I'd really like to know if there is a way to have two network cards in one computer, both being able to access the internet through different connections, but forcing Windows to use only the specific connection / gateway to the internet, while all intRAnet traffic uses the other.
 
I gave a general overview in my first post, but maybe it was not clear as to what I meant. On the NIC that is connected directly to the Internet you want to have a gateway set in the IP properties for that NIC. If your cable company uses DHCP then you do not need to do anything. As for the NIC that is connected to your internal network you will give it a static IP (DHCP will set a gateway for that NIC) and the appropriate subnet mask (probably 255.255.255.0 if you are using a 192.168.x.y network). Nothing else will be set for that NIC in the IP properties (no DNS or Gateway). This is one flaw with Windows is that it makes it look like each NIC should have a default gateway when there should only be one per any networked device.
 
Thanks nightowl. Previously I'd specified the same default gateway (modem) for both NICs. Leaving the intranet NIC's gateway blank worked. I just misinterpreted what you suggested.

Although I don't have this problem, how would I still allow DHCP to function for the intranet and maintain the correct default gateway? It just seems like I should have more control over how stuff is routed and configured in Windows.
 
Another problem has crept up now that I have the both the LAN and WAN connections working at the same time. I disconnect about every 20 to 40 minutes, and reconnect seconds later.
