How to Enable WAN Ping on a Linksys Router

Linksys routers disable the WAN ping function by default as a security precaution. When a host is connected directly to the Internet without a firewall in place, it presents a security risk because an attacker can learn of the host's existence through a ping sweep. It is not bad in itself for a host on the Internet to be pinged, as long as a firewall is in place. The Linksys router acts as a firewall for the rest of the network by default. You can enable the WAN ping on a Linksys router through the administrative interface.
