DESCRIPTION
In full cone 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 ZyXEL Device.
Select Dial on demand when you don't want the connection up all the time and
specify an idle time-out (in seconds) in the Inactivity Timeout field.
Clear the Dial on demand option to keep the connection up all the time. The
ZyXEL Device will try to bring up the connection automatically if it is
disconnected.
Only select this option if your service provider requires it. The following
conditions apply to a connection using PPP IP extension.
• Only one computer can be connected on the LAN.
• The ISP only assigns a single public IP address and the LAN computer uses
it on its LAN interface.
• The firewall and NAT features are disabled.
• The ZyXEL Device uses DHCP to tell the LAN computer that the ZyXEL
Device is its default gateway and DNS server.
• The ZyXEL Device extends the ISP's IP subnet to the LAN computer.
• The ZyXEL Device bridges packets between the DSL and LAN interface,
except for packets destined for the ZyXEL Device's LAN IP address.
If the ISP gave you a static (fixed) IP address, select this option and enter it in
the IP Address field.
If the ISP did not give you a static IP address, clear the Use Static IP Address
option. The ISP automatically assigns the WAN connection an IP address when
it connects.
Select this to have the ZyXEL Device keep trying to connect using the password
if there is an authentication error.
Select this to turn on the debug mode for the PPP connection.
This feature is available when you do not select PPP IP extension.
In addition to the ZyXEL Device's built-in PPPoE client, you can enable this to
pass PPPoE through in order to allow LAN hosts to use PPPoE client software
on their computers to connect to the ISP via the ZyXEL Device. Each host can
have a separate account and a public WAN IP address.
PPPoE pass through is an alternative to NAT for applications where NAT is not
appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the LAN to use
PPPoE client software on their computers to connect to the ISP.
