Your picture shows nothing about how you've set up the firewall rules. Please provide your firewall rules. Also I want to mention if that helps: "WAN to LAN rule should be on the FORWARD chain instead of INPUT or OUTPUT chain. INPUT chain is for the traffic that goes into the router itself and OUTPUT chain is for the traffic that comes from the router itself. You need to set a DROP rule with FORWARD chain and select the WAN interface as IN interface and LAN as OUT interface if you want to drop WAN to LAN traffic."

Post configuration export.
