IPv4 access control list

The IPv4 Access Control List is a specialized policy for denying IPv4 traffic based on:

• the incoming interface
• the source addresses of the traffic
• the destination addresses of the traffic
• the services or ports the traffic is using

The only action available in this policy is DENY.

This feature is available on FortiGates with NP6 processors and is not supported by FortiGates with NP6lite processors.
