I have a new windows 2003 server with ISA 2004 installed and three network cards. Network card 1 is connected to an SBS 2003 server SP1 ISA 2004 with 30 clients, network card 2 connects to a Fedora Core 3 machine and network card 3 connects to a XP pro machine running Virtual PC which has running 2003 server, 2000 adv server. Now the new ISA machine is the gateway and firewall and i need to know how to configure this. Network card 1 must have both way functionality for all standard services, Fedora 3 (network card 2) is port 80 only and network card 3 has windows update and outbound and RDP inbound. Can someone point in the right direction for setting this up please?
