Hi, I might be being really stupid here, but I am having trouble setting up an isdn router on a third nic to my server. I have three Nics, nic 1 is my private network, nic 2 is my router (leased line), nic 3 is the isdn router. I have static ip's on nic 1 (192.168.100.*;255.255.255.0) and I have configured nic 3 (isdn router nic) to (192.168.101.*;255.255.255.248). I have inserted nic 1 and nic 3 in to the LAT of the ISA server and can get onto the web interface of the router fine. As soon as I dial into the router from home I cannot ping any ip address except the isdn router address and the address that it has assigned me, I can't even ping nic 3. I have set up NAT on subnet one (192.168.101.*)in the router and IP routing on subnet two (192.168.100.*), with RIP on sub 1. I have also added a static route pointing all traffic to a terminal server throught the nic 1. Does this sound corret, or am I missing the plot terribly here. Maybe someone can give me a lesson in routing - :o). Thanks, Killjoy.
