ADSL ROUTER
USER MANUAL

Enable FullCone NAT
, all requests from the same private IP address and port are
mapped to the same public source IP address and port. Someone on the Internet only
needs to know the mapping scheme in order to send packets to a device behind the
ADSL router.
The gateway can be configured to disconnect if there is no activity for a specific period of
time by selecting the
Dial on demand
check box and entering the
Inactivity timeout
.
The entered value must be between 1 minute and 4320 minutes.
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.
Use static IPv4 IP address
, If the ISP gave you a static IP address, select this option
and enter it in the IP address field.
Bridge PPPoE Frames Between WAN and Local Ports
is available when you do not
use
PPP IP extension
. If you enable this function, LAN hosts can use PPPoE client
software on their computers to connect to the ISP. Each host can have a separate
account and a public WAN IP address.
