5.3 VPN
VPN(Virtual Private Network) is mainly used for setting up long-distance and/or secured network
connections. When used on DVX IPPBX, all phone calls made and received are encrypted so it
secures your remote offices/extensions' phone services. Built-in VPN Server on DVX series is an
easy way to set up a secured connection between other DVX series IPPBXs or IP phones. You
don't need to build a dedicated VPN server or buy a VPN router. This is also a workaround to
avoid firewall issues when configuring remote VoIP client such as SIP protocol which is
notoriously difficult to pass through a firewall due to its random port numbers to establish
connection.
DVX IP PBX supports four varieties of VPN, they are L2TP, PPTP, OpenVPN andIPSec.
5.3.1 L2TP VPN
L2TP VPN Server
Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol. It does not provide any encryption or
confidentiality by itself. Rather, it relies on an encryption protocol that it passes within the tunnel
to provide privacy. Here on the DVX IPPBX system we useIPSec to do the encryption.
To configure your L2TP server, navigate to web menu
