ACLs are a collection of permit and deny conditions, called rules, that provide
security by blocking unauthorized users and allowing authorized users to access
specific resources. ACLs can block any unwarranted attempts to reach network
resources.
The WAP Device supports up to 50 IPv4, IPv6, and MAC ACLs.

IPv4 and IPv6 ACLs

IP ACLs classify traffic for Layers 3 and 4.
Each ACL is a set of up to 10 rules applied to traffic sent from a wireless client or
to be received by a wireless client. Each rule specifies whether the contents of a
given field should be used to permit or deny access to the network. Rules can be
based on various criteria and may apply to one ore more fields within a packet,
such as the source or destination IP address, the source or destination port, or the
protocol carried in the packet.
There is an implicit deny at the end of every Rule created. To avoid deny all, it is
strongly recommended to add a permit rule within the ACL to allow traffic.
