Dear all I have isa server, and i can configure it as a gateway by simply [Enabling IP routing] in IP Packet Filters Properties when i connect my isa server on internet via LAN, by doing this, i just give the isa server machine's IP address in the node machines and every thing start working without any further settings, BUT, when i connect my isa server on dialup, then about configurations arn't works. Waiting the reply that if about configurations works on LAN properly then thats wrong when i comes on dialup? Mehfooz
