If your ISP blocks access to certain websites and services or if you are looking to bypass country specific restrictions to use services like Hulu and Pandora, using a Virtual Private Network (VPN) would be the best solution, majority VPN services are paid but today I will be sharing two free VPN services which gets the job done.
AlwaysVPN is a new
free VPN service currently in BETA offering secure anonymous connection through their servers via VPN clients for Windows XP, Windows Vista, Mac OS X and Linux (Ubuntu / Debian) , the service seems to allow unlimited traffic as it does not mention any limits on how much traffic can be used, However, advertising is shown on top of every webpage browsed through the AlwaysVPN network.
Not Free Anymore.
HotSpot Shield is another popular free VPN service offering clients for all major operating systems, unlike AlwaysVPN Hotspot Shield limits traffic to a maximum of 3 GB over a 30 days period.
Don't forget to uncheck the option to install conduit toolbar while installing HotSpot Shield to be on the safe-side.
