Windows Multihome Question

Hello:

I have an issue with Win 2003 server, network Load balancing, and Routing.

Set the Scene:

2 unique machines. Running Win 2003 Server and Cold Fusion. We had an
internal network and a DMZ

The machines have unique internal IP addresses on a /24 network.
The machine are NLB to a single IP in the DMZ.

The problem we have has to do with multihoming. We'd like to be able to
manage the machines remotely, which does require a default gateway on the
private side.

And of course the machines havea gateway on the DMZ side for HTP replies to
find their way out.

Currently we have a CFMHTTP request that is sent out thru the DMZ, and it
fails more or 90% of the time. However when we remove the gateway from either
the DMZ side or the private side, the request goes out, with no issue.

Is ther a way around this? Can Windows be coaxed into having 2 gateways on
two separate networks? Note that the only path between the networks is on the
machine itself. The networks are isolated for security reasons.

Thanx

You only use one Gateway and it must go on the External (DMZ) side. In the
Internal side you handle the routes to other internal subnets by using the
OS's Routing Table to create Static Routes.
