About VPN Service
VPN (virtual private network) service lets users connect to your network from home or
other remote locations over the Internet. Users make a secure VPN connection to
access workgroup services such as file sharing, mail, iChat, iCal, and web. VPN service
uses the L2TP protocol with a shared secret to ensure confidentiality, authentication,
and communications integrity.
