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 IP (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
this virtual interface.
Crypto Map entries are sets of configuration parameters

If there is no Crypto Map 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.
Use the URL Filter
drop-down menu to select or override the URL Filter
