Block Ping
Ping is a basic Internet program that, when used without malicious intent, allows a user to verify that a
particular IP address exists and can accept requests. Ping is used diagnostically to ensure that a host
computer you are trying to reach is operating. It can also be used to see how long it takes to get a response
back from a specific host computer.
Hackers can use ping to launch an attack against your network, because ping can determine the number
form of the network’s IP address (for example, 105.246.172.72) from the domain name (for example,
www.mynetwork.com). If you enable Block Ping, your network will block all ping requests.
To block ping:
• Open a Web browser and access the 2Wire gateway user interface by entering
http://gateway.2wire.net.
• Click the Firewall tab.
• Click the Advanced Settings link under the tab to open the Edit Advanced Firewall Settings page.
1. In the Security pane, click the Block Pings checkbox.
2. Click SAVE .
