Many large companies block all ports except 80, 110, 443 and 8080. Other 
ports are opened on a business need only basis and often to just a 
specific location. BTDT. I have had great success in such situations 
using SSH on 443. I could VNC over SSH to my Mac at home which could see 
the world. Funny thing, although such activities were against company 
policy, I can not count how many times I was asked if I could hit my 
home machine to see if a web resource was down or it was a corporate 
firewall problem before the help desk was called.
