• Services: Select the desired Service. This determines which packets are covered by this
firewall rule. If necessary, you can define a new Service on the "Services" screen, by defining
the protocols and port numbers used by the Service.
If you want to create a new custom service with incoming protocol and port (or range of ports)
here itself then select "Create custom service". Select TCP or UDP or TCP/UDP and then
enter incoming port or Range of Ports.
Start port should be between 1 to 65535 and Finish port should be entered only if you want to
allow range of ports. Ensure that Finish port is always greater than or equal to start port.

– ALLOW always
