Setting up encrypted HTTP Tunnel?

[Icebear]

So here at my Gym, there is a blockade on the routers, allowing very few ports to go through (blocking every online game, and serval sites).
At home I have an older Windows XP desktop computer which I can use as server. And then I'm using a MacBook for school work (and homeplay gaming). I've spent a lot of time trying to browse around on google, finding a proper, easily understandable guide (I havn't worked a lot with VPN/UTC connections)
Any that can show me a guide, or tell me how to with Software/Router portforwards. I've tried with the simple VPN setups, but they're getting blocked.
Currently programs such as HotSpot Shield (free, but way too unstable) and OpenVPN (Not so free) is working, most other VPN clients (for mac) is getting blocked behind the firewall.

Basicly:
Encrypted VPN/HTTPTunnel host from Mac/Windows 7
To
Encrypted VPN/HTTPTunnel server on Windows XP

Software+guide needed. Free would be prefered

Well basically you need VPN software that allows you to set the communications port.

OpenVPN (surely) can be configured to use port 80 (http) or 443 (https) and is available as open source for linux, mac and windows (not sure about your claim of it being not so free?)
You'll have to configure OpenVPN on both machines and enable port forwarding for the port you've chosen on your router at home.

Keep in mind that those blocks usually exist for a reason and someone might not be all too happy about you bypassing it.

If it block several sites, it probably blocks them by domain, rather than port (since all HTTP traffic is usually on port 80).

you will never get passed a firewall that blocks the ports LOL

Well not sites only, but as well as online gaming ports. Serval VPN/Tunnel programs can get through it.

I'll look into it, thanks.

You could try with udp port 123 (email port) for openvpn aswell.
