I have an IP that I picked up scanning my firewall for port 22 and I want to
block all traffic from this IP. Is it best to do this by rules like the
following or is there a better way:

REJECT    net:        fw         tcp          -
REJECT    net:       dmz       tcp          -
REJECT    net:       dmz        udp        -

(policy blocks all net -> loc)
