Connection Timed out: Connect at Log-In

Firstly, MERRY CRIMBO!
Secondly, I cant log in. Im normally I use my desktop and have no issues but IM over in my folks for christmas and in between getting fat and drunk as a lord I wanna leg in but I get that titular issue. Weird thing is I can log in at my home just not in my parents...
So im guessing its a router/firewall issue, SO. Things Ive tried
1. Comodo Firewall, gave rights to java, javaw, salem
2. Opened ports 1871/1870 (for both TCP/UDP)
3. cleared cache, reinstalled java, reinstalled client
4. tried both enders and standard client
5. punched the screen in frustration as im stuck at my folks with several hours to burn and not salem
My ip address here at my folks is 10.0.0.5 (weird right?), normally ive always seen it in the 192.168.x.x format so ive no idear whats going on...
HELP!
