I need to bridge two networks behind firewalls, and I happen to have
(actually spec'ed) a FreeBSD machine on each end.  My question is, has
this already been done, or am I on my own?

I don't see this in ports, so I suspect that I'm going to have to take a
crash course in the tun device.  I plan on looking at iijppp.  Where else
would I look for info on the tun device?
