The PPP IP Extension supports the following conditions:
Allows only one PC 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 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 only a single IP address to assign to a LAN
device.
NAPT and firewall are disabled when this option is selected.
The ADSL router becomes the default gateway and DNS
server to the PC through DHCP using the LAN interface IP
address.
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.
The ADSL router bridges the IP packets between WAN and
LAN ports, unless the packet is addressed to the router’s
LAN IP address.
