A running count of packets the firewall silently discarded, with no notification returned to the sender, because they matched a drop rule or the implicit cleanup rule. Unlike fwRejected, a rising fwDropped with no matching spike in logged connection attempts often points to background scan or probe traffic being silently absorbed, useful for distinguishing attack noise being handled from legitimate traffic being blocked by mistake. Example: fwDropped increasing by a constant few hundred packets per hour with no corresponding user complaints usually means the default cleanup rule is quietly discarding unsolicited internet background noise.
