Description: The number of connections attempted since the last reboot of the firewall, corresponding to the protocol denoted by 'cufwConnProtocol'.

This value is accumulated from the last reboot of the firewall.

What is cufwConnNumAttempted?

This is a 64-bit counter of connection attempts, since the last reboot, for the specific Layer 3/4 protocol identified by the corresponding cufwConnProtocol index entry. An admin drills into this per-protocol breakdown after checking the global total, to see which specific protocol -- TCP, UDP, ICMP, and so on -- is generating the bulk of connection attempts. For example, if the global attempted count is climbing, checking this table per protocol would show whether the increase is concentrated in, say, UDP traffic rather than spread evenly across protocols.
