ISA is designed for security, i know this. But i do not know a lot more.

Can it be installed on a server and then act as a router between all the NICs installed.

Or could i use the machine as a router (win server 2003) and then install ISA on it.

I wish to allow remote access to my internal network via VPN + imap for mail.

Can ISA be set:
2 static IP addresses from ISP
2 separate networks on own cards on internal network side.

So that both the external connections can link in to 1 local network on internal side.

Mainly because i wish all none email traffic through one IP address and MX records (mail) through another.
Mail server will be in internal network.

Does this make sense.
Do not wish DMZ for our mail server as too much hassle.

ISA is NOT a router - period. ISA has no concept of routing. What ISA DOES do is use the routing that has been setup pn the  underlying operating system.

Thanks for your answers. ISA does just use the underlying OS routing, I knew this. Anyway have found a cheap but nice hardware firewall unit that will do the job nicely + give me a couple of extra net ports i require. I know ISA would be better, but the management made me decide against it. I only really wanted to use it because have access to it. Thanks again.
