Iptables to filter traffic exchanged within the same wireless LAN

First set this in the hostpad config file:

ap_isolate=1

Also: disable_dgaf=1

Please read the config file for further details.

You may need this also:

iptables -A INPUT -p icmp -j DROP

It is even better idea to specify the name of the ethernet adapter so it doesn't affect the loopback adapter or any other adapters you may have.

iptables -A INPUT -i eth0 -p icmp -j DROP
