PPP IP Extension
The PPP IP Extension is a special feature deployed by some service providers.
Unless your service provider specially requires this setup, do not select it.
The PPP IP Extension supports the following conditions:
z
Allows only one PC on the LAN
z
The public IP address assigned by the remote side using the PPP/IPCP protocol
is actually not used on the WAN PPP interface. Instead, it is forwarded to the
PC’s LAN interface through DHCP. Only one PC on the LAN can be connected to
the remote, since the DHCP server within the ADSL router has a single IP
address to assign to a LAN device.
z
NAPT and firewall are disabled when this option is selected.
z
The ADSL router becomes the default gateway and DNS server to the PC
through DHCP using the LAN interface IP address.
z
The ADSL router extends the IP subnet at the remote service provider to the
LAN PC. That is, the PC becomes a host belonging to the same IP subnet.
z
The ADSL router bridges the IP packets between WAN and LAN ports, unless
the packet is addressed to the router’s LAN IP address.
Use Static IP Address
Unless your service provider specially requires this setup, do not select it.
If selected, enter your static IP address.
Enable PPP Debug Mode
Enable the PPPoE debug mode. The system will put more PPP connection information
in System Log. But this is for debug, please don't enable in normal usage.
