PPTP
PPTP is the acronym of Point to Point Tunneling Protocol. Usually, it is used to
encapsulate other protocols’ packets for transmission over IP network. Some ISPs use
this protocol as way to establish the initial connection between the CPE (end-user side)
and DSLAM (ISP side). If your ISP uses PPTP to establish the connection, you should
select this item and follow the steps below.

Connect-on-demand:
It is a utility used to trigger the PPTP session when there
is packet being sent through the WAN port while it is on
disconnected situation. Check the radio button to make
this function active, and then you must enter the number
of minutes you wish the network to remain idle before
disconnection occurs in the “Max Idle Time” location.
Keep Alive:
This function keeps your PPTP connection enable even
if it remains idle. However, in some situation, PPTP
session cannot be established immediately after
disconnection. This is because the system on the ISP’s
site may need a little time to restore itself. You may need
to check with your ISP to obtain detail of how long you
need to wait before re-establish the PPTP session. Enter
