the modem router to respond to a ping to its WAN (Internet) port.

View or change the following settings:

Disable IPv4 Firewall Protection. The IPv4 firewall is enabled by default, which is 
the recommended setting. Some advanced users might want to disable IPv4 firewall 
protection to examine the traffic coming in from the Internet.

Disable Port Scan and DoS Protection. DoS protection protects your LAN against 
denial of service attacks such as Syn flood, Smurf Attack, Ping of Death, and many 
others. Select this check box only in special circumstances. 

Default DMZ Server. This feature is sometimes helpful when you are playing online 
games or videoconferencing, but it makes the firewall security less effective. See 

Respond to Ping on Internet Port. This feature allows your modem router to be 
discovered. Use this feature only as a diagnostic tool or if you have a specific reason.
