Relakks encrypts all traffic from your computer to the Internet by using a VPN connection which means that your real IP is not revealed on the Internet at all. The service had serious troubles in the beginning; users were unable to connect to Relakks at all, had slow connections and email support was terrible. Well, they apparently are making a comeback by emailing past users inviting them to freely test Relakks once again for seven days without charges.
I decided to try it out once again and was able to signup again with their service. You have to configure a new VPN connection in your operating system which is explained in the faq section of their website. Details are provided for Microsoft Windows XP, Vista and Mac OS X. Even beginners should be able to create a VPN connection this way. You can now choose to automatically use Relakks whenever you connect to the Internet or manually activate the service, I decided to use it manually but it does not make a difference as long as the service is running.
