stop a freebsd server from responding to pinging?

1. How do I stop others from port scanning a server?

2. is stopping the response to pinging enough?

3. how to do I stop the server from responding to
pinging?

Running FreeBSD 4.2 and 6.1.

I changed the /etc/rc.network file to "NO" for
broadcast ping responses, and this did not work (still
responding to ping) when I rebooted:


case ${icmp_bmcastecho} in
[Yy][Ee][Ss])
echo -n ' broadcast ping responses=NO'
sysctl net.inet.icmp.bmcastecho=1
/dev/null
;;
