We also looked at that product as a firewall for our administrative
network. One major drawback: Network Address Translation is required
between the inside and outside interfaces. It is a proxy server at heart
(it's really just MS Proxy Server 3.0) and it cannot act like a router
between those interfaces.

It can in fact route packets without terminating the TCP connection
between the 'DMZ' and the outside interface, but traffic destined for
the inside interface must be proxied.

Those reasons, among others, caused us to go another route.
