This article explains how to block Pings (ICMP).
This information applies to:
BlackICE PC Protection and BlackICE Server Protection version 2.9 and higher. (Formerly BlackICE Defender for Workstation and BlackICE Defender for Server)
Answer By default, the software does not block pings. However, you can edit the firewall.ini file to tell BlackICE to block pings. REJECT statements must be manually added to the [MANUAL ICMP....] section of the firewall.ini. If this is a new installation, the file will be located at CProgram Files/ISS/BlackICE. If you have an older version of BlackICE that has been updated, the path will be: CProgram Files/NetworkICE/BlackICE
This statement will block all ICMP Echo traffic for all IP addresses.
REJECT, 8:0, ICMP, 2001-10-15 00:01:00, PERPETUAL, 1000, MANUAL
