ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N
The service numbers for many common protocols are defined by the Internet Engineering
Task Force (IETF) and published in RFC 1700, Assigned Numbers. Service numbers for
other applications are typically chosen from the range 1024 to 65535 by the authors of the
application.
Although the wireless VPN firewall already holds a list of many service port numbers, you are
not limited to these choices. Use the Services screen to add additional services and
applications to the list for use in defining firewall rules. The Services screen shows a list of
services that you have defined, as shown in the following figure.
To define a new service, you need to determine first which port number or range of numbers
is used by the application. You can usually determine this information by contacting the
publisher of the application, user groups, or newsgroups. When you have the port number
information, you can enter it on the Services screen.
 To add a customized service:
1. Select Security > Services. The Services screen displays. The Custom Services table
shows the user-defined services. (The following figure shows some examples.)
Figure 71.
2. In the Add Customer Service section of the screen, enter the settings as explained in the
