Re: Multihomed Win2k Server Routing Issue

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

you have two issues here.
 
1. Routing. If you do not want to add route in the cisco router, you can use route command on 192.168.1.x computer pointing them to the 192.168.3.x.
 
2. NAT blocking the traffic from 192.168.1.x to 192.168.3: Since you enabled the NAT, one (I am assuming it is 192.168.1.250 ) you may setup as public and 192.168.3.250 is private. Now, what the NAT does (like firewall) blocking all trafiics from outside, in your case it is 192.168.1.x.

So the only way to fix this is to add another route to the Cisco
Router? That's fine, and I intend to give that a go, but I'm STILL
wondering why I can't use 192.168.1.250 (server NIC) as the default
gateway for all of the machines in the 192.168.1 subnet. When I do,
there is no internet for those machines, and STILL no being able to see
or ping machines in the 192.168.3 subnet. Ideally, that is what I'd
like to have happen.

For some reason, that 1.250 NIC ignores all routing requests thrown at
it, but it IS listed as a routing interface in Routing and Remote
Access Applet on the server.

In short, the 192.168.3.250 server NIC acts as a gateway for the .3
subnet just fine, why won't the 192.168.1.250 server NIC do the same
for the .1 subnet?

Thanks for the help so far, much appreciated.
