Luci only on lan ( not wifi)

method 1

  • First, create the network/DHCP/Firewall Zone
  • Then browse to WiFi settings
  • Select the new network
  • Save and Apply

or method 2

(BTW, not sure why you showed the second pic if you choose to make a new network, you don't need to setup a firewall rule if you're making a new network that will be blocked anyway.)

And I noted you would select Advanced and select the WiFi PHY, not Zone:

:spiral_notepad: If you use the firewall method, you would make an Input Rule to block inbound DST 80 and 443/tcp to the router.
