VPN (Virtual Private Network) is a private network established on the public network (generally the Internet).
However, this private network logically exists only and has no actual physical line. Therefore, it is called VPN. VPN
technology allows employees in a branch to conveniently share LAN resources of other employees or the
headquarters without exposing these resources to users on the Internet.
VPN establishes a virtual private line between two sites using tunnel technology. It uses end-to-end
authentication and encryption to ensure data security. Tunnel protocols supported by this router include Layer 2
tunneling protocols PPTP and L2TP and Layer 3 tunneling protocol IPSec.
4.5.1 PPTP/L2TP Client
The PPTP/L2TP client supports connection from the VPN router client to the VPN router server. For example,
information simple and safe access between the branch and the headquarters is required. This can be achieved by
using the VPN server function in the router in the headquarters and the VPN client function in the router in the
branch.
