I have a network that I am installing ISA on. I have 5 machines that will need to be accessed by external machines. I currently have it setup so ISA Server has 6 NIC's. The 5 NIC's have a different IP address to be able to route to a secific Internal IP address. The Citrix Server, for example, has a static 10.0.0.5 address and is using the ISA DNS server for resolution internal and external. The ISA server has the external IP address binded to one of the 6 NIC's so when I put in a request for the citrix server IP address it goes right there. This works great but If I have to have a NIC for each internal server on my network that needs to be able to be accessed from and external source I'm gonna go crazy. I found a tech note on microsoft's website and citrix's website that I should route it all through the one external nic. I guess what I'm thinking is like the NAT when you can bind an external IP address to an internal one. Is this possible or am I going crazy and just can't see it or what? Any help on this would be appreciated. I also have a PC anywhere machine that I want to be able to access from externally and I want to be able to go out as well. I have been unsuccessfull and figured I would ask this as well to save myself a little bit of time if possible. Thanks for the help in advance.
