As just a user, I can´t really oversee the advantages of VPN. It´s necessary, that´s all I know. But as a german user of VPN I´m very disappointed, that VPN doesn´t cooperate with german Telekom mail. Telekom said it´s a problem with AVG and AVG told me it´s a problem with Telekom. Theres no solution in sight. It´a pity.
