Hi Frank,

You can negate the match !192.168.2.0/24, the IP set has a checkbox for it. Then you can block all traffic except the internal network.

Or you order the rules, to have the allow to 192.168.2.0/24 and them deny all outgoing traffic. 

Either of the above needs to be done for the incoming traffic.

Cheers,
Alwin
