Playing Diablo 3 behind a proxy?

Does anyone know if this is possible?

I tried changing the "Internet Options" for the computer but it only seems to work on the launcher.

Solution 1:

Try using Widecap http://www.widecap.com/ - it's freeware and works fine, not just with games, but with all kind of network software

Proxifier http://www.proxifier.com/ - I play many game through it. Everything is ok.

You could also choose one of other proxifiers http://en.wikipedia.org/wiki/Comparison_of_proxifiers
