I have heard of ISPs NATting their customers, but I think it would be  
pretty unusual these days. Does the high-port forwad to port 22 on  
your PC? Or is the PC listening for ssh? See /etc/ssh/sshd_config for  
that one.

How are you testing ssh'ing to your external IP address? Doing so  
from inside the LAN won't work - you're better port-scanning yourself  
by visiting Shields Up! at http://grc.com

You can get a hostname which will resolve to your dynamic IP at  
http://dyndns.com - there are some free utilities which you can run  
to do the updating.
