Event ID 20096 — RAS Connection
Applies To: Windows Server 2008 R2
A server running Routing and Remote Access provides two different types of remote access connectivity: virtual private networking (VPN) and dial-up networking. VPN is the creation of secured, point-to-point connections across a private network or a public network, such as the Internet. A VPN client uses special TCP/IP-based protocols called tunneling protocols to make a virtual call to a virtual port on a VPN server. In dial-up networking, a remote access client makes a nonpermanent, dial-up connection to a physical port on a remote access server by using the service of a telecommunications provider, such as analog phone or ISDN. In contrast to dial-up networking, VPN is always a logical, indirect connection between the VPN client and the VPN server over a public network, such as the Internet.
