This is important, proxy clients dont connect to the net, they ask the
NT box to fetch in information and then the NT delivers it to the
clients.

M$ Proxy does not NAT, so it's normal that you can't get out.

Same as above, the FreeBSD box does not have a valid IP (this is based
on your email).

Well, the only solution I see is to setup the FreeBSD box with 2 NICs,
install NAT and FIREWALL, and a DHCP Client (/usr/ports/net/ics-dhcp2).
Correct me if I'm wrong here, I think this port contains the server and
a client... right?

That will be possible once the FreeBSD box will have a routable IP.

From what I understand, they "connect" via M$ proxy, right? Installing
the Firewall, using the "simple" setup, and NAT will allow you to do
that.

ICQ will not work, but maybe someone else could cut in here with some
more details.. Concerning the rest, everything should work fine.

See above.
