Hi Sub, Why? Why not bind each IP address to the external interface of the ISA firewall and then publish resources as required. I think the problem here is that you're not asking the right questions and we're not giving the right answers. What is it that you're actually trying to accomplish?

ISA2004 as a router? http://www.ISAserver.org For me the scenario is as follows: One ISP with multiple publics IPs bound to the circuit; 24.106.55.82 - 86; gateway 24.106.55.81. The circuit is delivered to my office via their router. I want to attach a single Ethernet cable from the ISP router to the ISA 2004 Enterprise server and then segregate the public IPs to several subnets. Ideally each public IP would come from each NIC to a switch and connect to hosts from there. The ISA2004 Enterprise server is current and patched. The machine is a dual xeon 2ghz with 4gb of ram running w2k3. It has 10 NICs installed. I'm off to read Chapter four in depth. Thanks.
