Hi I have a satellite connection which acts as a return path. The satellite software drivers install the card and make it appear as a new NIC. I dial up to my ISP using a modem and then establish a VPN connection to my ISP. All return traffic is then routed through the satellite. This all works fine without ISA installed. As soon as I install ISA it doesn't work. I have tried turning on Routing and Remote Access and setting up a new VPN interface. However when I look in the logs it seems that ISA is blocking everything that arrives on the satellite NIC. Any one have any ideas as to how I get this to work? Thanks in advance Bernard
