IP ACL
An IP ACL consists of a set of rules which are matched sequentially against a packet. When
a packet meets the match criteria of a rule, the specified rule action (Permit/Deny) is taken
and the additional rules are not checked for a match. On this menu the interfaces to which an
IP ACL applies must be specified, as well as whether it applies to inbound or outbound traffic.
Rules for the IP ACL are specified/created using the IP ACL Rule Configuration menu.
