2.12. Configuring PPTP
PPTP (Point-to-Point tunneling protocol) supported by APOS™ complies with RFC2637
standard.
If PPTP server can be accessed thorough LAN interface, Virtual Private Network can be
configured by using PPTP.
PPTP supported by AddPac VoIP gateway is a client function which enables a user to access to
PPTP server. Therefore PPTP server must exist in Internet.
Previously, VoIP and data were used to be transmitted though the tunnel by command of ‘PPTP
route tunnel’. However, Only VoIP can be transmitted though the tunnel by using a new
command of ‘PPTP route data’.
The following configuration must be taken first to transmit only VoIP packet through the tunnel
and data packet to WAN.
Detailed configuration process can be verified in ‘Related Commands’ section.
(config-ether0.0)# encapsulation ppp
Some of AddPac Technology VoIP gateway series can support this feature.
