Dual NIC questions

I have a Server 2003 machine running SQL Server 2005. It has two
network ports on it. We are developing on the machine with one port
plugged into our internal network. However, I also want to start
testing applications where it needs to be outside the router NAT'ing so
it is directly available. I thought that if I plugged the outside
connection into the other network jack, and set the IP address to the
correct one of the static IP that I own for it, everything would work.
NOT. Programs inside the box register for traffic on a specific port.
Do they also specify a NIC? I assume that the inbound traffic from both
would all funnel in the same way, and outboud would be bsed on the
subnet mask and the destination IP. Can anyone shed light on making one
server handle traffic from two NICs with different IP subnets?

Great question, I pretty much asked the same thing 2 posts ago. Still
no answers. I will be watching both of our post in hopes for some
practicle answers! GL!
