The IPCop Firewall is configured by using Services and/or Service Groups.
If you want to create a rule for a Service that is not present in the list of Default Services, you will have to add it first.
In first section you give the custom Service a descriptive name, choose the Protocol and Ports (TCP and UDP only).
Note
Use the Invert option with great care, as this can create far larger holes in your IPCop Firewall than you might expect!
The second section lists the custom services you have added.
