About port lists
Port lists are collections of ports, port ranges, or port lists that can be assigned to firewall rules.
Firewall rules use port lists to allow or deny access to specific ports in IP packets. They compare a packet's source port and/or destination port with the ports in a port list. If there is a match, the rule takes an action, such as accepting or dropping the packet. Port lists must contain at least one entry. You cannot create an empty port list; you cannot remove an entry in a port list if it is the only one.
