Networking - Multi-homed.

[Brian]

I have a Windows 2000 Server with two network adapters in it running
Terminal Services.

One adapter is a 10 network and the other adapter is a 192 address.

Users access the terminal services server through the 10 network. I would
like to direct all web traffic that is local from the server out the 192
network adapter. The problem is the 10 network card is the default gateway
so all traffic continues to travel out this adapter. If the default gateway
is changed to the 192 network everything works fine, other than now no one
can access the terminal services.

Any ideas on how I can achieve this type of configuration?

It's simple. No, you can't do that. The paths taken (which includes the
source interface) is determined by the OS's Routing Table. Routing Tables
have no concept of "web traffic".

And routing tables can not be edited ?

There has to be a lot more info provided before saying it can't be done,
such as 'where are the terminal services being accessed from ?'. Intranet,
InterNet ? If the server has a 10. and a 192. NIC, then what device is
actually providing internet access ?

Maybe this will help to clarify further.

Users access the system through the 10 network. When the user opens a
terminal services session - I would like to proxy the 192 address in
Internet Explorer and send that traffic out the 192 adapters Gateway. All
remaining traffic returns out the 10 network - the default gateway.

Not really.

Not really.

Agreed,...not really.

You can direct routing based on destination subnet, but you said "web
traffic" which would imply HTTP or FTP. Routing tables do not acknowledge
these types of protocols which are Application Layer Protocols, so you
cannot "route" based on them. You can direct them down a different path by
using "proxy settings" in the browser *if* you have a CERN Compliant Web
Proxy to do that with, but you haven't indicated that you have such.
