Remote access to the Raspberry Pi

Goal: Log in to the Pi from WAN.
Problem: Pi is on the LAN without 192.. address, and my Cable provider changes my WAN IP address from time to time.
Solution: Sign up with a dynamic DNS service, and set up a little program on the Pi that frequently posts its WAN address to the service.

It's dead simple with, and described neatly here on their support page.
Dynamic DNS Help and Support - No-IP

Of course, something needs to be listening on a port. So that port needs to be forwarded from the router to the Pi. I have a AVN Fritz!Box, which has a config page for such things. So for instance, to allow ssh access, you'd forward port 22 to port 22 on your Pi.

Works flawlessly on my setup!
