Description: icmp connections passing through the FireWall-1 Module
What is fwConnectionsStatConnectionsIcmp?
The desc explicitly states this is the number of ICMP connections passing through the FireWall-1 Module right now. Since ICMP is normally just pings and error messages, this number is usually small; a sudden large value is a classic sign of a ping flood or an ICMP-based reconnaissance sweep against hosts behind the firewall. e.g. ICMP connections spiking to 5,000 during a network scan, versus a baseline of a few dozen.
