How to Enable WAN Ping on a Linksys Router

By Jedadiah Casey

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.

Step 1

Open a browser, then type "192.168.1.1" (without quotes) into the address bar. Press "Enter."

Step 2

Leave the user name blank and type "admin" for the password. Press "Enter."

Step 3

Click "Security."

Step 4

Click to uncheck "Filter anonymous Internet requests."

Step 5

Click "Save Settings" to apply the changes.

Tips & Warnings

  • Though the router can now be pinged from the Internet, it is still acting as an SPI firewall to help protect the network.
