IPv4 is a connectionless protocol for packet switched networking. IPv4
operates as a best effort delivery method, since it does not guarantee
delivery, and does not ensure proper sequencing or duplicate delivery
(unlike (TCP). For more
information on creating IPv4 firewall rules, see Setting an IPv4 or IPv6 Firewall Policy.
IPv4 and IPv6 are different enough to warrant separate protocols. IPv6
devices can alternatively use stateless address autoconfiguration. IPv4
hosts can use link local addressing to provide local connectivity.
Use the IPv6 Inbound Firewall
Rules drop-down menu to select the IPv6 specific inbound firewall
rules to apply to this profile‘s virtual interface configuration.
Click the Create icon to define a new IPv6 firewall rule
configuration, or click the Edit icon to
modify an existing configuration.
IPv6 is the latest revision of the Internet Protocol (IP) replacing IPv4.
IPV6 provides enhanced identification and location information for systems
routing traffic across the Internet. IPv6 addresses are composed of eight
groups of four hexadecimal digits separated by colons. For more information on
creating IPv6 firewall rules, see Setting an IPv4 or IPv6 Firewall Policy.
