When I started writing this, I thought that system had been abandoned
already, but it appears Microsoft will offer a measure of support
through next year sometime.  Do see that the system gets properly
updated before you put it on the net.

The keyword is that you need to set up your machine as a gateway.
There are numerous guides available on how to do that (including the
FreeBSD Handbook (free, online and likely already on your system) my
PF tutorial (http://home.nuug.no/~peter/pf/) contains more than a few
hints, as do several books available at better bookstores), but I
would recommend that you pick literature that enables you to learn the
basics of TCP/IP as well as the actual commands needed.  Looking into
packet filtering for basic protection won't hurt either.  With those
keywords in hand, you should be able to dig up something useful.
