dialing *99# from my laptop gets me this.

from my laptop 10.153.102.41 to my work desktop

[joelja@joelja-vaio joelja]$ ssh -l joelja twin.uoregon.edu

[joelja@joelja-vaio joelja]$ ssh -l joelja blotto.ath.cx
ssh: connect to host blotto.ath.cx port 22: Connection timed out

I haven't had any joy working through t-mobile on why they do this but it 
sucks and it makes my phone (nokia 3650) a lot less useful. Yes blotto 
has an ssh on an alternate port but that means hauling eveything back 
through there instead of being able to just connect back to the   whatever 
host I want.
