Use this screen to configure firewalls. The firewall inspects
packet traffic to and from connected clients. If there is no
firewall rule that meets the data protection needs of this
virtual interface, select the Create icon to define a new firewall rule
configuration or the Edit icon to modify or override an existing
configuration. For more
information, see Wireless Firewall.
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

configuration that meets the needs of this virtual interface, click the
Create icon to define a new Crypto Map configuration or
click the Edit icon to modify an existing configuration. For more information, see
Overriding VPN Configuration.
