To configure the PPPoA or PPPoE settings:
Enter the User’s PPP
Username
and
Password
.
Enter
the
Service Provider Name
if any.
Select
the
Authentication Method
used during negotiation, default is AUTO.
Check to enable “
Fullcone NAT
”. A full cone NAT is where all requests from the
same internal IP address and port are mapped to the same external IP address
and port. Any external host can send a packet to the internal host, by sending a
packet to the mapped external address.
If you do not need PPPoA or PPPoE connection always ON, check “
Dial on
Demand
” and enter the timeout value to disconnect the PPPoA or PPPoE
connection when connection is idle and timeout. If you enter zero (0) for the
timeout value, it means always ON.
Check
the
“
PPP IP extension”
if your ISP requests to enable it, otherwise do not
select it. This is a special service to forward IP address assigned by remote to
the local device in the LAN.
Check the “
Use Static IP address”
and enter the IP address if your ISP assigns
a fixed IP address to you. Otherwise, do not select it.
Check to enable “
Retry PPP Password on Authentication Error
”.
Check to enable “
PPP Debug Mode
”.
The box “
Bridge PPPoE frames between WAN and Local Ports
” is checked in
default. (This option is only available in PPPoE mode.)
