2-3-4 Setup procedure for 'PPTP xDSL':
PPTP xDSL requires two kinds of settings: WAN interface setting (setup
IP address) and PPTP setting (PPTP user name and password).
We start with the WAN interface settings:
Select how you obtain IP address from your service provider here. You
can choose 'Obtain an IP address automatically' (equal to DHCP, refer to
'Cable Modem' section above), or 'Use the following IP address' (i.e.,
static IP address).
The WAN interface settings must be correctly entered, or the Internet
connection will fail even if the PPTP settings are correct. Contact your
ISP if you don't know how you should fill in these fields.
Connection Type - There are 3 options:
"Continuous’"- keep the Internet connection alive, do not disconnect.
This is the preferred choice for "always on" / "Flat rate" Internet
services.
"Connect on Demand" - only connects to the Internet when there’s a
connect attempt. This is the preferred choice for all users who have
paid per minute Internet Service or per transferred data.
"Manual" - only connects to the Internet when the ‘Connect’ button on
this page is pressed, and disconnects when the ‘Disconnect button is
pressed.
