I've gone through about 2-3 days of constant searching for this, and have tried many different approaches, but I fear I simply don't understand enough about VPN's to be able to do this without asking for help. Searching suggestions on superuser also yielded me nothing of use.
So my problem is this: My college campus blocks almost all ports, I can still access the internet, use programs such as Teamviewer, however other programs such as Steam, or Origin are blocked. I'm looking for a way to connect to a VPN server that is setup on my home computer (running Windows 7) from my college campus, so that all the campus firewall knows is that I'm connecting to my home's IP address, and all of the data for my internet usage is routed though the VPN. I understand windows has a built in PPTP service, but all of my attempts to set this up have failed. Not sure what other information is needed. Both computers are running windows 7 Home Premium, and my home's cable router (technically I believe it's a wireless gateway) is an Arris Touchstone Telephony Wireless Gateway Modem TG862G.
EDIT: Figured I'd share the error message I'm met with when attempting to connect to VPN from laptop. http://gyazo.com/e4d943eaf0b42f4cd2d52fe614a17d71
EDIT2: Tried the "Diagnose" button shown in the picture above, met me with this: http://gyazo.com/a3031b5a06d84ffe2d9e00a5aebd12e0 Seems like it's telling me that the ports are blocked on the host computer, however I can verify that I have in fact port-forwarded 1723 to my host computers local address. Not sure why it isn't responding. Is a wireless gateway simply incapable of routing a VPN connection to the host computer?
EDIT3: I'd like to make clearer that I am not looking for a simple web-broswer proxy server to run off my home PC. I want all programs on my laptop to be routed through a VPN to my home PC, not just a web browser.
