Firewall 69 Universal Plug and Play Universal Plug and Play is a technology that offers seamless operation of voice messaging, video messaging, games, and other applications that are Universal Plug and Play compliant. Some applications require the Router's firewall to be configured in a specific way to operate properly. This usually requires opening TCP and UDP ports and in some instances setting trigger ports. An application that is Universal Plug and Play compliant has the ability to communicate with the Router, basically "telling" the Router which way it needs the firewall configured. The Router ships with the Universal Plug and Play feature disabled. If you are using any applications that are Universal Plug and Play compliant, and wish to take advantage of the Universal Plug and Play features, you can enable this feature. Simply select On in the Universal Plug and Play section of the Utilities page. Click Apply to save the change. 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, select Block ICMP Ping and click Apply; the router will not respond to an ICMP ping from the Internet. Remote Administration Before you enable this function, ensure that you have set the Administration Password. Remote Administration allows you to make changes to your Router's settings from anywhere on the Internet. You can choose to either: ■ Click the check box to enable any PC on the network to remotely manage your Router ■ Enter one specific IP address that can remotely manage your router. This is more secure, as only the specified IP address will be able to manage the Router
