Configuring the Gateway
Defining an application profile
An application profile allows application-specific data to pass through the firewall. You
can define an application profile that is not included in the application list. 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.
1. Open the gateway home page at http://192.168.1.254.
2. Click the
Settings
tab, then click the
Firewall
tab.
3. Click
Applications, Pinholes and DMZ
.
4. Scroll down to the Edit Firewall settings for this computer pane.
5. Scroll down and click
Add a new user-defined application
.
6. Enter the following information:
•
Application Profile Name
. A descriptive name for the application profile.
•
Protocol
. Select TCP or UDP. If the application you are adding requires both,
you can create a separate definition for each.
•
Port (or Range)
. The port number or range of port numbers that the
application uses. For example, some applications requires only one port to be
opened (such as TCP port 500); others require that all TCP ports from 600 to
1000 be opened. If only one port is required, enter the port number in the From
field.
•
Protocol Timeout
. The amount of time in seconds that can pass before the
application times out. If the field is blank, the gateway uses the default values
(86400 seconds for the TCP protocol and 600 seconds for the UDP protocol).
•
Map to Host Port
. A value that maps the port range you established in the
Port field to the local computer. For example, if you set the value to 4000 and
the port 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, and so on.
•
Application Type
. Select the application type. If you do not know the
application type, leave the field blank.
7. Click Add to List.
