Protecting Your Network
5-11
Incoming traffic from the Internet is normally discarded by the gateway unless the traffic is a
response to one of your local computers or a service that you have configured in the Port
Forwarding or Port Triggering menu. Instead of discarding this traffic, you can have it forwarded
to one computer on your network. This computer is called the Default DMZ Host.
To assign a computer or server to be a DMZ Host, from the main menu, under Advanced, select
DMZ Host. Enter the IP address of the computer you would like to assign as a DMZ Host and click
Apply. To disable the DMZ Host, enter “0” and click Apply.
Respond to Ping on Internet WAN Port
If you want the gateway to respond to a 'ping' from the Internet, click the ‘Respond to Ping on
WAN Port’ check box. This should only be used as a diagnostic tool, since it allows your gateway
to be discovered. Don't check this box unless you have a specific reason to do so.
Enabling or Disabling Content Filtering Services
You can use the Services page to disable certain gateway features. To disable a feature, remove the
check box from its Enable check box.
When Firewall Features are enabled, the gateway will perform Stateful Packet Inspection (SPI)
and protect against Denial of Service (DoS) attacks.
When VPN Pass-Through is enabled, IPSec and PPTP traffic will be forwarded. When it is
disabled, this traffic will be blocked.

The Services page is only accessible while logged in as a parent.
