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 about the source of the connection (5-tuple).

Note: The ability to send traffic based on destination only is required by some applications. Enabling this feature may not allow some on-line applications to work properly.

To enable strict UDP session control:

•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 Strict UDP Session Control checkbox.

2.Click SAVE.
