Service Objects

  • Last updated on

The  Services  view allows you to view and configure service objects. Create service objects to reference IP protocols and, if TCP/UDP is used, the destination port numbers, when configuring access rules. When creating a new service object, you can also include (reference to) other  service objects that are already configured. To access the Services window, click Services under the Configuration menu on the left.


Default Service Objects

In the Service Objects list, a number of objects are available by default. For example:
