I don't believe that's true. The document plainly states that the firewall allows others on
the 'Net to reach servers on your LAN that would otherwise be unreachable. Others on
the 'Net contact your firewall IP address, which is dynamic, and the firewall redirects the
requests via NAT and port redirection to the internal server(s).

Now, I agree that others need some way of reaching the dynamic IP address of your
firewall. And I believe that can be accomplished via a Dynamic DNS (DDNS) service.
My Netgear router/firewall supports this. That is, even though I have a dynamic IP
address, I can set up my router to provide DDNS registration. Specifically, I must: 1.)
register my domain with a DDNS; and 2.) input the DDNS service data into the router
setup. Then, my router will contact the DDNS and re-register my dynamic IP with the
DDNS every time the address changes.

End result: The outside world can reach my LAN servers inspite of my dynamic IP
address in front of them.

Now I don't think I'd want to do all this for my system. But it is possible. Those who must
have servers on their system, but who are forced to use a dynamic IP, can set it up this
way and overcome.

I think all of the above is right??
