IP Routing Across Dual-homed 2003 Server

I have a 2003 server with two NICs. Subnet X connects directly to a router
for Internet access (via NIC X). Subnet Y connects to a LAN switch (via NIC
Y). The default gateway for NIC X is the Internet router, which can
successfully access the Internet. My question is, how can I get an XP client
to have Internet access when routed through the 2003 server. I setup IP
routing on the 2003 server with a static route to subnet X from subnet Y
(where the XP client resides). The default gateway for the XP client is NIC
Y on the 2003 server. The client can ping NIC X, but cannot ping the router
for the Internet. Again, I'd like to know how I can setup the NICs and/or IP
routing on the 2003 server to enable the XP client to access the Internet?

make sure you have enabled IP routing. or post the result of ipconfig /all
here may help.

This is a limitation of default routing. Once you get two routers it
usually fails. Your Internet router has no route to your inner subnet (it
does not have a interface in that subnet) so it doesn't know how to get
traffic to it.

You will need to add a static route to your Internet router telling it
to forward traffic for your inner subnet to the Windows router. The only
other option is to use NAT, and that will prevent routing between the local
subnets.

I didn't hear you say "RRAS". You need RRAS on the box to make it function
as a LAN Router. then you need to add the Static router to the Internet
Sharing Device as Bill said.
