So if you want a VPN that listens on port 443 then OpenVPN is probably the way to go, as already 
suggested.  You could also probably use SSH port forwarding or other methods from [1].  All of which 
depends on your firewall not proxying SSL/TLS or looking too closely at the traffic.

OpenVPN already uses SSL/TLS so probably it fits the bill.  If you actually need HTTP at some point 
there seem to be ways to do that (http://www.nocrew.org/software/httptunnel.html).  There also seem 
to be a lot of web pages that take your name/password to set up a VPN, so maybe there are other ways 
to do it too (those are likely not Free though).
