[Tfug] DynDNS howto

[Matt Jacob]

As Jeremy said, you need to log in to your router's configuration site
(usually 192.168.1.1 or 10.1.1.1 or 172.16.1.1) and then look for the
section with port forwarding. Sometimes it's called "forwarding" or
"port forwarding" or "applications & gaming", but they all do the same
thing. You plug in a port number (80 for HTTP, 22 for SSH, 25 for
SMTP, etc.) and then tell the router which local computer that traffic
should be directed to.

Sometimes the setting will be called "port range forwarding". That's
fine too. In that case, you'll just enter 80 for the starting port and
80 again for the ending port. For protocol, you can either pick "TCP",
or just leave it on "both". If there's a checkbox to enable the
forwarding rule, make sure you check it. :-) You might have to restart
your router in order for the forwarding to take effect, but that's
unlikely.

Good luck!
