Connecting remotely - no input for ip address?

I have a Squeezebox Radio I'm trying to setup in the hopsital for my girlfriend while she's in there.

I goto, Settings>Advanced>Networking.. I connected to the hospitals wifi with no problems.

Under Remote Libraries where I would normally put my IP address, it's not allowing me to use every number. The first octet set only allows me to use the characters, 1, 2, and 0. I can't enter any other number.

I managed to get it connected to mysqueezebox.com and playing music that way but I'd like to connect to my servers IP.. Is there a bug? Is it setup for IPv6 or something? I'm so confused but either way it doesn't seem I'm able to put in my IP address..

Anyone have any ideas?
