Firewall Tab • In the Applications panel, click the Add a new user-defined application link to open the Edit Application page. Figure 18. Edit Application Page Firewall Tab 1. In the Application Name field, enter a name for the application profile. You can enter any name you like, although it’s recommended that you use the name of the application (for example, Redwing Game Server). 2. In the Definition panel, create a definition for your application. A definition consists of a series of protocol-specific ports that are to be allowed through the firewall. This information should be contained in the documentation provided by the company that produces the application. a. In the Protocol field, select the TCP or UDP radio button. If the application you are adding requires both, you must create a separate definition for each. b. In the Port (or Range) field, enter the port or port range the application uses. For example, some applications may require only one port to be opened (such as TCP port 500); others may require that all TCP ports from 600 to 1000 be opened. c. In the Protocol Timeout (seconds) field, you may optionally enter a value for the amount of time that can pass before the application “times out.” You can also leave the field blank, in which case the system uses the default values (86,400 seconds for the TCP protocol; 600 seconds for the UDP protocol). d. In the Map to Host Port field, enter a value that will map the port range you established in step b to the local computer. For example, if you set the value to 4000 and the range being opened is 100 to 108, the forwarded data to the first value in the range will be sent to 4000. Subsequent ports will be mapped accordingly; 101 will be sent to 4001, 102 will be sent to 4002, etc. e. From the Application Type drop-down menu, select the application type. If you do not know the application type, select None (Default). 3. Click ADD DEFINTION to add the values to the profile definition list. 4. Click DONE. Repeat these steps for each port or range of ports required for the application profile. To edit or delete an application profile: • Open a Web browser and access the 2Wire gateway user interface by entering • Click the Firewall tab. • Click the Firewall Settings link under the tab to open the Edit Firewall Settings page. Firewall Tab • In the Applications panel, click the Edit or delete user-defined application link. The Select a Hosted Application page opens. Figure 19. Select a Hosted Application Page 1. In the User-Defined Application Profiles panel, highlight the application you wish to edit or delete. f. To edit the application profile, click EDIT. The Edit Application screen appears. Make the necessary changes to the application profile and click DONE. g. To delete the application profile, click DELETE. Allowing all Applications (DMZplus) DMZplus is a special firewall mode that is used for hosting applications if you cannot get an application to work properly using the “Allow individual application(s)” option. When in DMZplus mode, the designated computer: • Shares your gateway’s IP address (Router Address). • Appears as if it is directly connected to the Internet. • Has all of the unassigned TCP and UDP ports opened and pointed to it. • Can receive unsolicited network traffic from the Internet. Although the computer in DMZplus mode appears to Internet users as though it is directly connected to the Internet, it is still protected by your system firewall. All traffic is inspected by the firewall’s Stateful Packet Inspection engine and all known hacker attacks continue to be blocked. Firewall Tab Because all filtered traffic is forwarded to the designated computer, you should use DMZplus mode with caution. A computer in DMZplus mode is less secure because all available ports are open and all incoming Internet traffic is directed to this computer. To configure DMZplus: • Open a Web browser and access the 2Wire gateway user interface by entering • Click the Firewall tab. • Click the Firewall Settings link under the tab to open the Edit Firewall Settings page. Figure 20. Edit Firewall Settings Page 1. From the Select a computer pull-down menu, select the computer to which you would like to have all data sent. 2. Click Allow all applications (DMZplus mode). Firewall Tab 3. Click DONE. 4. Access the computer that you selected in step 1. 5. Confirm that the computer is configured for DHCP. If it is not, configure it for DHCP. 6. Restart the computer. When the computer restarts, it receives a special IP address from the system and all unassigned TCP and UDP ports are forwarded to it. To stop DMZplus: 1. From the Select a computer pull-down menu, select the computer for which you would like to disable DMZplus. 2. In the Edit firewall settings for this computer pane, click Maximum protection. 3. Click DONE. 4. Access the computer that you selected in step 1. If the computer will continue to automatical...
