Problem connecting from behind a proxy

You are on the right track, you need to enable the single port option
and then change the port to 80. On your firewall you will need to
forward port 80 to your home machine.
HOWEVER: Many corp firewalls/proxies do more than just check port
numbers, sometimes they also scan the contents of the traffic, meaning
that if it doesn't look like HTTP then it will fail. One possible
alternative to this is to try Port 443 instead of 80. This is the
Secure web site traffic port and will likely pass through most
proxies. If this is not the case then you might not want to persue
this. Corporate IT departments have standards for a reason, it may
not be wise to violate them.
