I have an NT 4.0 server acting as a firewall/proxy server. This is being handled by Alta Vista Firewall 98 s/w. There is a private and public card in this server. The private card's default gateway is itself, the public card is using the router as a default gateway. I can get out to the Internet from that particular server,but no where else on the network. I can ping that same server from anywhere on the network. Any ideas? Thanks.
