I would suggest installing APF fire wall, then do this:
pico -w /etc/apf/conf.apf
Change this:
IG_ICMP_TYPES="3,5,11,0,30,8"
To this:
IG_ICMP_TYPES="3,5,11,0,30"
So, if you have a monitoring service, add the monitor's IP to the alallow_hosts.rules file.
THEN:
service apf restart
That would block pings from all outside sources except the IP's you explicitly allow.
