The
PPP IP Extension
is a special feature deployed by some service providers. Unless your
service provider specifically requires this setup, do not select it. If you need to select it, the
PPP IP Extension supports the following conditions:
It allows only one computer on the LAN.
The public IP address assigned by the remote using the PPP/IPCP protocol is
actually not used on the WAN PPP interface. Instead, it is forwarded to the
computer's LAN interface through DHCP. Only one system on the LAN can be
connected to the remote, since the DHCP server within the ADSL gateway has
only a single IP address to assign to a LAN device.
NAPT and firewall are disabled when this option is selected.
The gateway becomes the default gateway and DNS server to the computer
through DHCP using the LAN interface IP address.
The gateway extends the IP subnet at the remote service provider to the LAN
computer. That is, the PC becomes a host belonging to the same IP subnet.
The ADSL gateway bridges the IP packets between WAN and LAN ports, unless
the packet is addressed to the gateway's LAN IP address.
