36 Setting up your wireless router To set MAC Address Filtering: 1 Open the Firewall > MAC Address filters page, then click Enable MAC Address Filtering. 2 Enter the MAC address of each computer on your network by clicking in the space provided and entering the MAC address of the computer you want to add to the list. 3 Click Add, then click Apply Changes to save the settings. You can have a MAC-address-filtering list of up to 32 computers. Note: You will not be able to delete the MAC address of the computer you are using to access the router's administrative functions (the computer you are using now). Enabling the Demilitarized Zone (DMZ) The DMZ feature lets you specify one computer on your network to be placed outside of the firewall. This may be necessary if the firewall is causing problems with an application such as a game or video conferencing application. Use this feature on a temporary basis. The computer in the DMZ is NOT protected from hacker attacks. If your ISP subscription provides you with additional public (WAN) IP addresses, additional computers can be placed outside the firewall provided each computer uses a different public (WAN) IP. To set up a DMZ for a computer: • Open the Firewall > DMZ page and enter the last digits of the computer's IP address in the IP field, click Enable, then click Apply Changes for the change to take effect. 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 from the IP address, a hacker can determine that something of interest might be there. The router can be set up so it will not respond to an ICMP ping from the outside. This heightens the level of security of your router. To turn off the ping response • Open the Firewall > WAN Ping Blocking page and select Block ICMP Ping, then click Apply Changes. The router will not respond to an ICMP ping.
