Use the IPv4 Inbound Firewall
Rules drop-down menu to select the IPv4 specific inbound firewall
rules to apply to this profile‘s virtual interface configuration.
Click the Create icon to
define a new IPv4 firewall rule configuration, or click the Edit icon to
modify an existing configuration.
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).
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 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 Configuring IP Firewall Rules.
Use the VPN Crypto Map
drop-down menu to select or override the Crypto Map configuration applied to
