I am trying to understand ACLs and am unsure of where they are applied.
Here's my example. I am trying to prevent communication between two VLAN interfaces.
My source clients are on VLAN 1, my destination servers are on VLAN 2. I want to prevent the clients from communicating with the servers. I am only able to apply inbound ACLs.
Do I apply the ACL on the VLAN 1 interface or the VLAN 2 interface?
