Can you create a FreeBSD gateway, with private IPs, without NAT/divert ?

[Tom Pusateri]

I've seen this setup with IPv4 before when the ISP does native IPv6. Maybe you can get global IPv6 addresses and can SSH directly over that. If not, at least go on record requesting IPv6 with your provider to push them along.

Well, the problem is I am trying to use sshuttle, which inserts it's own set of divert rules into the ipfw table ... so I have one natd_enable, and a set of divert rules ... and then we add another set of divert rules from sshuttle (which does not, btw, start it's own natd).
