Routing failures using 2 NICs and w2k srv

[Friday]

Pulling my hair out because I thought this would be easy. Boy was I wrong.

Here goes my setup:

Installed 2 NICs, both with IPs setup properly

Went into the registry in enabled Ip Forwarding, and a ipconfig /all reports Ip forwarding as yes.

NIC #1:
IP 10.176.251.50
SM: 255.255.255.0
GW: 10.176.251.150

NIC#2
IP: 204.224.246.200
SM: 255.255.255.0
No gateway.

The NIC on the 10.xxx side is able to ping all of the 10.xxx address on the network. The Nic on the 204 side is also able to ping everything on the 204.xxx network


Now, on a PC on the 10.176.251.xxx side, I entered a route add command as follows:

route add 204.224.246.0 mask 255.255.255.0

This allows me to ping the NIC#2 on the server, but nothing else on the 204 side, just the 204.224.246.200 NIC on the server. This is killing me since I feel clueless and info on the net doesnt seem to address this problem. Even reproduced the failures with my system at home. Frustrated!!

Im assuming you have the Routing and Remote Access Service installed. If you don't, install it and enable NAT.
That should end your problems.

Do the machines on the 204.224.246.0/24 side have a route back to the 10.176.251.0/24 side? You'll have to add a route for both sides of the connection. Also, the route command for a machine on your 10.x subnet is 'route add 204.224.246.0 mask 255.255.255.0 10.176.251.50 metric 1', you left off the gateway(next hop). Only install NAT if you're sure thats what you need, seems you wanted regular routing instead of nat'ing the 10.x subnet.
