Disallow ICMP requests. You only need that open for diagnostic purposes. Only allow ICMP when you MUST test the connectivity.
Hope it helps

how do i disallow ICMp ?
I assume your running a firewall that your using to block all the other open ports. You would need block ICMP as well.
If your not using a firewall then please give some more info like what OS your running etc.
