This Counter64 counts connection setup attempts, scoped to the protocol/policy/target combination in cufwPolConnProtocol, cufwPolConnPolicy, and cufwPolConnPolicyTarget, that were aborted before completing, including aborts initiated by the firewall itself as well as by either endpoint. An admin can use it to see how often a specific policy's connections are failing to fully establish for reasons beyond simple policy denial. A high value here for a policy applied to a remote-access target, for instance, could point to network instability or client-side issues interrupting the handshake rather than the policy blocking the traffic outright.
