Windows 2003 Server, 2 NICs, 2 Gateways

I've investigated this for awhile, and found little to no good clear answers.  Many answers said "buy cisco", or something along those lines.  It dosn't seem that it's that big of an issue, but aparently it is.

My Setup:
Webserver (Win2k3) - NIC1 (, NIC2 (
Router #1 - Sonicwall -
Router #2 - Cisco PIX -

Currently, I have all my hosting running thru Router 1.  I'd like to have some of the services/websites running off Router 2, but I can't because of the one default gateway rule.

I'm not a huge routing person, and I don't understand why I can't install 2 NIC's with two different gateways.  In my mind, it seems simple that if a request for a page comes in and hit's ip 1.51, to respond via that NIC.  If something comes in to 1.50, respond via that NIC.  I don't get why that won't work.  Am I missing something?

Thanks for any thoughts/ideas/suggestions.

The issue, I think, has more to do w/ two nics and default gateways residing on the same network.  Could you try this:

Put router one on /
Put router two on /

Put nic1 on / gateway
put nic2 on 1921.68.2.51 / gateway

See if that works the way you want to .

Yes, that does work, but now I have two separate networks.  I was hoping to be able to pull this off w/out separating them.

I was hoping to be able to make some sort of adjustment on the server that basically told it to respond from the NIC it received the request from.

Unfortunately, I believe the server adjustment would be subnetting which is going to create two networks.  Is there a reason to avoid two networks?  You could always setup a router between the two networks, if needed.

I wanted to try to pull it off w/out subnetting because then I'd have to reconfigure my network, and I didn't want to do that if I didn't have to.  But, looks like I don't really have a chose.

Thanks for the help!
