Ok. Oh, and please don't tread the net using a 'root' name, it confuses me
and some mail user agents out there.

Ok, the trick is, the internet knows that when it sees 18.104.22.168, that
packet should be delivered to your Linux box. When it sees 22.214.171.124,
it will either deliver it elsewhere, or drop the packet.
However, you CAN assign certain ports on your Linux box to be forwarded to
your server, this is called reverse NAT, or reverse masquerading in a
You might set this up like this:
ipnatctl -I -p tcp -d 126.96.36.199 --dport 80 --b destination -t 10.0.0.3
This would process a connection coming from the internet to your linux
server, port 80, such that it would end up at port 80 of your server. If you
want it to arrive at another port, use the --to-port n feature.
It may even work without specifying a port to use, in which case it might
RNAT *all* connections to your server. I'm not sure about this.
Hope this helps..
