You only want one default gateway defined so you would leave the NIC with the 192.168.2.1 address with a blank default gateway. Then your only default gateway is 192.168.111.9 Then you do a route add for the subnet 192.168.2.0 and tell it which interface to use (192.168.111.12) and what address to send that traffic to (192.168.111.9).

I'm running into an issue on my Windows 2000 (SP4) server where internet traffic is being sent out the default gateway. Doesn't sound like a problem, but the default gateway is wrong. The machine has two NIC's, each belonging to a different internal network with different gateways. I need one of those networks to be the default route for all traffic, and the other used only for traffic destined to that specific network.

How do I change this? I've looked through the registry keys located at HKLM\SYSTEM\CurrentControlSet\Services\Tcpip and found no mention of how to change this. I've attempted to change the interface metric and gateway metric settings within the TCP/IP properties of the NIC's themselves, but this has no effect on the default gateway. I've attempted to change the last route listed (since it is the only route that is unique to a given address). The error it gives me when I try to add a duplicate route to the last one listed is "route: bad destination address 255.255.255.255. I've read through the Windows 2000 TCP/IP implementation details and could not find the specifics on how to change this. Is it simply a route I need to modify for this value to change? Is there a way to change this? Thanks! Nathan Grandbois Cerdant, Inc. 614.717.0123 ext. 26 PS> If anything isn't clear, let me know and I'll be more detailed.
