Single protocols and ports can be merged to a service to simplify the configuration and maintenance of the firewall. Some of the most common services are predefined. You can add or edit the services list as you need.
A service contains the following information:
• | Name: A name for the service to recognize it when use it within rule definition. |
• | Protocol: Network protocol (must be used). |
• | Source port: Is not necessary at most of the services because it is chosen at random. |
• | Destination port: Port 80 for http for example. |
