Hi

This is a regular FreeBSD question, therefore probably off-topic for 
this list, but I'm asking people anyway.

Under some conditions, I will need to either:

1. Drop all of the firewall's NAT'ed connections for a certan LAN IP.
2. Ban all traffic from a LAN IP address for a certain amount of time.

Does anyone know if this possible through commands in m0n0wall? I need 
to invoke them from exec.php or exec_raw.php.

Best regards,
Jan Nielsen
