Service filtering
Service Filtering allows you to select what types of packets are
able to pass through the WMG. In Service Screen, you could see
the list of all pre-set services. If to add more services, select “Add”
to specify more services.
To define a service, first determine which port number or range of
number is used by the application. Common applications are
defined by IETF. Service numbers for other applications are
typically chosen from the range of 1024 to 65535 by the authors of
the application.
Type in the Service Name you wish to call, the assign the
corresponding service port either by single and range type. If you
know that application uses either TCP or UDP, select the
appropriate protocol. Click “Add” to add more service rule. All the
service rules will appear on the Access Control, Inbound/Outbound
policy menu, the destination port selection.
