Hello
I am looking for a iptables rule, which blocked the complete access to the Wan interface via the MAC address. So that my tv in the Lan is attainable but no connection to the Wan (Internet) has. Can someone tell me how the rule would look?
I have already tried the following, but unfortunately without success.
Thanks
Oxbow

Iptables -I FORWARD -i br0 -m mac -mac-source 00: 00: 00: 00: 00: 00 -j DROP

Iptables -A PREROUTING -i br0 -m mac -mac-source 00: 00: 00: 00: 00: 00 -j DROP
