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.
Note: If you configure the firewall to block an Inbound protocol, you may disable support for hosted applications that require that type of protocol.
To block an Inbound or Outbound protocol:
•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 Inbound and Outbound Control pane, deselect the checkbox of the protocol you wish to block.
2.Click SAVE.
Disabling Attack Detection
By default, the 2Wire gateway firewall rules block the attack types listed in the Attack Detection pane. There are some applications and devices that require the use of specific data
ports through the firewall. The gateway allows users to open the necessary ports through the firewall using the Firewall Settings page. If the user requires that a computer have all incoming traffic available to it, this computer can be set to the DMZplus mode. While in DMZplus mode, the computer is still protected against numerous broadband attacks (for example, SYN Flood or Invalid TCP flag attacks).
In rare cases, the incoming traffic may be inadvertently blocked by the firewall (for example, when integrating with external
