Configuring Advanced Firewall Settings
The Edit Advanced Firewall Settings page allows you to configure advanced features on your firewall.
Enabling Advanced Security
The 2Wire gateway firewall already provides a high level of security. You can configure the firewall to provide
advanced security features, including stealth mode, strict UDP, or block pings.
• Stealth Mode. When in stealth mode, the 2Wire gateway firewall does not return information in
response to network queries; that is, it will appear to hackers who are trying to access your network
that your network does not exist. This discourages hackers from further attempts at accessing your
network, because to them it will appear as though there is no active network to access.
• 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. 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.
