Weh. The IP address my VPN runs on has changed; and the only port I have open is for the VPN, not SSH.
I can't SSH into the server (or into the Pi, /then/ to the server) to change the VPN config files... damnit.
...and nobody at home knows how to open ports, so I can't really ask them to do it.
I should really set up a dynamic DNS of some sort. Or at the very least have the Pi check http://icanhazip.com once or twice a day then email me if/when it changes.
