tri-homed Windows 2003 server

[FAS]

Are there any issues in using a Windows 2003 Server as a tri-homed router?
The 1st NIC (172.16.1.1) is connected to LAN, 2nd NIC (192.168.1.1) is
connected to a different LAN, while the 3rd NIC (1.1.1.1) is connected to
the Internet. However, we would like to have some public IPs (eg, 2.2.2.x)
rerouted to 2nd NIC (192.168.1.1), instead of going thru the 3rd NIC where
the default gateway was defined. Any tips on how to do this efficiently?

There is really nothing different about RRAS in this respect. But it is
a problem for any router because of the way IP works. To connect private
networks to the Internet you need to use NAT or a proxy server. These are
designed to give the private addresses access to the public network. They do
not work in the other direction - you cannot access the private network from
the public side.

It may be possible to do what you want, but there is not enough info in
this post to suggest anything.
