In FMC, there is a easy way to block IPs that are hitting your Firewall, Right Click, Block IP. My understanding is that the IP is put in the Global-Block-List (Objects>Security Intelligence>Network Lists and Feeds).
My question is, can you reference that Global Block List in an Extended ACL object? Reason being, I created an extended ACL to block traffic at the control plane to block VPN attempts. It would be very helpful if, when i see an IP trying to brute force into the FW or attack it, that once i right click and block the IP, its automatically in the Extended ACL at the Control Plane level too.
Any way to do this?
