GN-B41G Wireless Broadband Router
The VPN Pass Through Tab
A Virtual Private Network (VPN) is a type of secured private network connection,
built upon publicly-accessible infrastructure such as the Internet. Typically,
VPNs employ a certain combination of encryption, digital certificates, strict user
authentication and access control to provide security to the data they deliver.
They usually provide connectivity to various devices behind a gateway or
firewall.
The GN-B41G supports Internet-industry standard technologies to provide open
and interoperable VPN solutions, including Internet Protocol Security (IPSec),
Layer 2 Tunneling Protocol (L2TP) and Point-to-Point Tunneling Protocol
(PPTP).
PPTP Pass Through setting
Point-to-Point Tunneling Protocol (PPTP) allows you to establish a
connection to an enterprise network. With PPTP, if your device is
located within a local network, you can share files and other data.
IPSec Pass Through setting
IP Security (IPSec) provides authentication and encryption. Since it is
mainly a Layer 3 technology, it can secure all data on the network. It has
become a standard protocol used with Virtual Private Networks (VPNs).
L2TP Pass Through setting
Layer 2 Tunneling Protocol (L2TP) is an extension of the Point-to-Point
Tunneling Protocol and is also used to establish virtual private networks.
