Hamachi behind a corporate firewall blocking my hamachi

"I have not used hamachi until now, but I think that if it's based on a TCP or UDP connection, you simply have to change the ""listening port"" on the home machine to something like 80 or 443, so the corporate firewall will think it's a legitimate connection.

(I think that the corporate firewall doesn't do deep packet inspection, so that you really can't do that)

Later edit:
You can also try encapsulation of the hamachi traffic over an ssh tunnel, so you have to connect hamachi
