Enabling Advanced Security
Your 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
In normal firewall operation, when an unknown remote device makes a request to connect to a user’s 
network the firewall does not allow the connection to be made and responds with a “connection not 
available” message. This may not discourage a determined...

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...

Strict UDP Session Control
Enabling this feature provides increased security by preventing the 2Wire gateway from accepting packets 
sent from an unknown source over an existing connection.
Strict UDP instructs the 2Wire gateway to be more restrictive about what packets are allowed to transmit 
over an established connection from a local network computer to the Internet. In addition to relying on 
information about the destination (3-tuple), the 2Wire gateway will also use information...

Allowing Inbound and Outbound Traffic
The Inbound and Outbound Control pane displays some common protocol types. When one of the Inbound 
protocol boxes is checked, the firewall allows the corresponding protocol to pass through from the Internet 
to the network. If one of the Outbound protocol boxes is checked, the firewall allows the traffic from the 
network to pass through the firewall to the Internet.
To block an Inbound or Outbound protocol:
 Open a Web browser and access the 2Wire...

Management and Diagnostic Console
This chapter describes the 2Wire gateway Management and Diagnostic Console (MDC). The Management 
and Diagnostic Console provides information about the status of the 2Wire gateway, its broadband network 
connections, attached home networking devices, system and security information, and a running log of any 
error conditions.
You can use the tools provided to:
 View configuration and ser vice provisioning information.
 View operation logs.
 Perform diagnostic tests....
