You can combine related IP addresses into an IP Group. For example, if you want to block traffic from three separate IP addresses, you do not have to create three separate firewall rules. Instead, you can combine the three separate IP addresses into a single, configurable IP Group. Then, when you create a firewall rule, you can pick the newly created IP Group as your Source. You can use the same practice for Destination IP addresses. For more information, see Create an IP group.
Similar to an IP Group, you can create a Service Group to combine similar port requirements.
