Game-players frequently designate one computer on their LAN as
a DMZ (Demilitarized Zone), and allow all internet traffic to pass
through the firewall to that computer.
To set up a filter for online gaming or to create a DMZ, see
Chapter 2, Online Gaming on page 16.
Make these entries on the WAN IP Filter page of your
Configuration Manager:
Index A number 1-7 that will identify this filter
configuration.
To associate a filter with an Internet
connection, use the WAN IP Filter field on the
WAN Settings page.
NAT Network Address Translation. If this check box
is selected, the modem uses its WAN IP address
as the source address for outgoing packets.
NAT must be enabled if you are using private
IP addresses on the LAN.
NAT is enabled by default. If it is disabled,
computers on the LAN must have public IP
addresses.
Enable If this check box is selected, the rule is enabled.
Use Address
Passthrough
If selected, lets you open up one computer on
the LAN to all traffic allowed by the filter rule.
This allows teleconferencing or game-playing
over the Internet, for example.
LAN IP
Address
Required if NAT is enabled. If NAT is not
enabled and this field is left blank, the ADSL
Ethernet does not use the destination address.
WAN IP
Address Optional. If blank, the ADSL Ethernet does not
use the source address when it matches packets
against the filter rule. If an address or subnet
specification (for example, 202.68.84.0/24) is
entered, the ADSL Ethernet uses the 202.68.84
(network) part of the address to filter packets.
Protocol Lets you select tcp, udp, all, or a tcp/udp
application.
