I hope I'm in the right forum for this kind of question. I'm in China and as you're probably all aware, the Great Firewall (GFW) blocks a lot of websites. Surprisingly, when using the IPv6 connection provided by CERNET (academic university network), I can bypass GFW and access blocked websites such as google, youtube, facebook, twitter, ...
Unfortunately, not all websites support IPv6 yet, so disabling IPv4 is not an option as it makes lots of websites inaccessible (also Skype won't work without IPv4).
Is there an easy way to proxy/tunnel/whatever all IPv4 traffic through my IPv6 connection? I found a website, sixxs.net, that kinda does what I'm searching for, but I'd like to have this functionality on an OS-level (like a VPN).
Any tips are welcome!
