MTU
The Maximum Transmission Unit the DSL connection can send. It is a negotiated
value. The PPPoA interface default MTU is 1492 (max) and PPPoA default MTU is
1500 (max). The minimum MTU value is 64.
On Demand
Enables On Demand mode. The connection disconnects if no activity is detected
after the specified idle timeout value. When checked, this field enables the
following fields:
•
Idle Timeout
•
Host Trigger
•
Valid Rx
Default
Gateway
If checked, this WAN connection acts as the default gateway to the Internet.
Enforce MTU
Check this box if you experience problems accessing the Internet over a PPPoE
connection. This feature will force all TCP traffic to conform with PPP MTU by
changing TCP Maximum Segment Size to the PPP MTU.
The
Enforce MTU
feature is enabled by default. It forces all TCP traffic to conform
with PPP MTU by changing TCP maximum segment size to PPP MTU. If it is
disabled, you may have issues accessing some Internet sites.
Debug
Enables PPPoA connection debugging facilities. The
Debug
option is used by ISP
technical support and ODM/OEM testers to simulate packets going through the
network from the WAN side.
PPP
Unnumbered
Specifies that the calling and answering routers will not request IP addresses.
PPP Unnumbered is a special feature. It enables the ISP to designate a block of
public IP addresses to the customer where it is statically assigned on the LAN
side. PPP Unnumbered is, in essence, like a bridged connection.
LAN
The LAN field is associated with the PPP Unnumbered field and is enabled when
the PPP Unnumbered field is checked. You can specify the LAN group the packets
need to go to when the PPP Unnumbered feature is activated.
