Hi, I have an ISA Server with 3 networks cards in, on external interface to the internet. The second for subnet1 (192.168.1.x), the third for subnet2 (192.168.2.x). At the moment from the 192.168.1.x side you can ping its own subnet1 and 192.168.2.x (subnet2). From the 192.168.2.x side you ping its own subnet2 but not 192.168.1.x (subnet1). How can I get ISA/RRAS to route the packets on the subnet2 to subnet1? ISA is configured so that the external network has a gateway address of our internet router, the subnet1 and subnet2 gateways are both blank. Can anybody shed any light to this matter? Kind Regards, Chris Bond
