We have an ISDN router on our network that is not directly connected to the server running ISA server. (but they are on the same network) I have configured the server's default gateway to the IP address of the router, yet I cannot connect from a client machine with the web browser setup with "connect through proxy" to browse the internet. It reaches the ISA server and then I get an URL error (12202). Is there something that I am missing?? I feel I have checked all possibilities of problems. As far as I can tell ISA server is very easy to setup, can someone give a list of very basic setup steps that I can check. thanks, all help will be greatly appreciated. regards, Corran
