Question : Adding static routes / dual default gateways to a windows 2003 server

Hi i have a windows 2003 server with 2 nics,

Nic 1 has an eternal facing ip address which goes directly to the outside world and has a software firewall behind it. This is the main nic and is used for most traffic including exchange (ip 83.170.111.112 , gateway 83.170.111.1 , subnet mask 255.255.255.0)

Nic 2 has a watchgaurd firewall infront of it providing dhcp, which gives it an internal ip address and is to be used for rdc and backup purposes. (ip 10.0.0.51 , gateway 10.0.0.1, subnetmask 255.255.255.0)

I'm not sure how to get traffic through Nic 2  flowing properly as i know server 2003 will not operate with a dual default gateways. My question is how do i get both of these cards up and running on the internet using different gateways. If i need to setup static routes for nic 2 can someone please send me wolly instructions on how to do this

Thanks in advance

Answer : Adding static routes / dual default gateways to a windows 2003 server

Hello Mark,
Sorry for the late reply here.  I was out with the stomach flu first, then a nasty cold second.  All during a life-critical go-live at the hospital I work at!  So it's been a bit crazy around here.  Anyway, thanks for the netstat post.

The 0.0.0.0 address listing in your netstat means all IP addresses regardless of what NIC they are on.  So that looks good, it means that IIS is listening on all IP addresses, and therefore listening on both NICs.

How about running a trace route from both ends?  The webmail client to the server and the webmail server to the client?

If you can set up the server so NIC1 is primary, and then run tracert and capture that output here too, that would be helpful.  Try the reverse as well, whatever your client IP address is, try the tracert from the server to that IP address.  This should show us if there's a routing loop, and also what gateway the server and client are trying to use, and whether those are correct or not.  If you can post the output of each, that would be helpful in case there's some information that's helpful in there.
