don't forget plain old 'disabled' in current code.

do you want to block just ping or all unicast communication ?

are clients in same vlan or multiple vlan ?

I want to allow ping and also allow all unicast traffic.

I read the question wrong, I thought you wanted to block ping, anyways as suggested set the peer-block action to forward upstream and test.

following this config
