62 CHAPTER 5: ROUTER CONFIGURATION
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 Enable in the UPnP Enabling 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
