Specifying IP Addresses for Firewall Rules

You can allow only communication with devices that have the specified IP addresses and reject communication with other devices. You can specify a single IP address or a range of IP addresses.
Up to 4 IP addresses (or ranges of IP addresses) can be specified for both IPv4 and IPv6.
The communication protocols that can be restricted in this way are TCP, UDP, and ICMP.
