Viewing Your Firewall Summary

The Firewall Summary page provides summary information and links to the most commonly used security-

related features of your system.

•

Click the

Unsolicited inbound traffic is not allowed to pass through the firewall.

Custom.

Applications are associated with computers on your network.

An access list shows the computers (Devices) on your network and the names of the Allowed Applications

for each computer. When you allow application traffic, external users on the Internet can have limited

access to your home network. This access might be required to allow some programs (such as game

servers or instant messaging software) to operate properly.

For example, a remote game player on the Internet might need to contact the game server program that you

have installed on your home network in order to play against you. Normally, the firewall blocks this

communication. By changing the firewall settings, this communication is permitted to pass through a

“pinhole” in the firewall. This function may be referred to as “port-mapping” or “port-forwarding” in your

software program documentation.

Updating the Application Profile List

If the application you want to host does not appear in the Application Profile list, you may need to update

the application list. If an update is available, the

UPDATE APPLICATION LIST

button appears above the list of

application profiles. If the application that you want to host is not included in the updated application list,

you may need to add your own application profile.

Adding an Application Profile

If you wish to host an application that is not included in the Application Profile list, you can add an

application using the Add Application Profile page.

An application profile configures your system’s firewall to pass through application-specific data. This

feature is typically used if the application for which you would like to pass through data to a given computer

is new or has been recently updated to a new version.

To create a new application profile:

•

Open a Web browser and access the gateway user interface by entering

•

Click the

Firewall

tab.

•

Click the Firewall Settings

link under the tab to open the Edit Firewall Settings page.
