Thanks Michael, I'm aware of this.  This is partly why it would prefer a
router with a built-in NAT firewall and port-forwarding.  I can
obviously do the samething on Ubuntu server with a modem, but its never
a good idea to have your firewall and protected applications on the same

Of course an alternative would be to have the machines connect
automatcally to a central server.  But then the central server needs to
redirect the user from its web-server to the web-server on the remote
machine via the VPN tunnel... I don't even know if that's possible or
whether it would require a Phd to set it up?!
