Yep, this is why NAT is evil and bad in every way except for extending the life of IPv4.<BR>
<BR>
OpenSSH supports VPN tunneling similar to how OpenVPN works (and I don't just mean standard port forwarding).<BR>
Here is a link discussing it<BR>

Nope, that doesn't seem to be the confusion here. His ISP has him behind NAT,
so he doesn't have a public IP that can be connected to.
Take my situation:
firewall external IP address is assigned by my DSL router via DHCP as
192.168.254.2
The DSL router gets a "public" IP of 192.168.254.254 from the DSLAM.
Something upstream does NAT. The IP that I see on the other end of my link is
74.38.80.1. Hitting a website like whatismyip.com gives me a random IP in
74.38.80.0/24, but I can't connect back to that IP from a remote host, stuff
just dies at whatever is doing NAT.
