Is there a way to block the Ethernet(LAN) port of a wireless router?
I'm not trying to block a particular device, so black listing the mac address is not an option. I just want to block any device through Ethernet(LAN) port, but should be allowed via WLAN.
If it's unable through software, a hardware solution would also be fine without permanently damaging or completely removing. (like applying some thing to the pins so the connection between the cable and the port would not be established)
