4.10 WAN Setup
Clicking on the “WAN Setup” sub-heading in the “Advanced” list will take you to the “WAN Setup” page.
This is where you can enable or disable the router’s DMZ, Internet Ping, and HTTP-related items.
4.10.1 Demilitarized Zone (DMZ )
The DMZ feature allows you to specify one computer on your internal network to be placed outside the
firewall. This may be necessary if the firewall is causing problems with a game, video conferencing, or
other application. Use this feature on a temporary basis. The computer in the DMZ is NOT protected from
hacker attacks.
4.10.2 WAN Ping Blocking
Computer hackers use what is known as “pinging” to find potential victims on the Internet. By pinging a
specific IP address and receiving a response, a hacker can determine that something of interest might be
at that IP address. You can set your router so it will not respond to a hacker’s ICMP ping, increasing the
level of security provided by your router.
If it is necessary to turn on the ping response, select “Allow Ping Response on WAN port” and click
“Apply”..
4.10.3 Disable NAT
This feature disables all NAT router functionality.
4.10.4 Enable Access to Router Managemnet via Internet
This feature allows users with access to the Wi-Fi network to login to the router interface. Be aware that
the default settings “username and password” = “admin” a good security measure against intruders to your
network. If you wish to restrict the access to the router interface to be accessible only via ethernet cable,
please uncheck this box.
