	OK.

	For that the jail needs it's own public IP address.

	No, because you need each one to have ports 21, 22, 25 ... open
independently.

	In that case there's only one set of public ports. You *can* run
some services on non-standard ports but email won't for one. You're SOL
unless you can get more public IP addresses to use.

	If IPv6 addresses will do for public then you can always tunnel an
IPv6 connection from Hurricane Electric - it's free and you get a /64 and
if you want it a /48 to use. I think they're the only tunnel broker left
that still provides tunnels on request.
