packet-tracer input <interface> <protocol> <src-ip> <src-port> <dst-ip> <dst-port>
Cisco command line output looks like this:

It doesn't need to look much like the Cisco output, but, what would be mst helpful. would be listing each rule it was processed against in order of processing, up until it is allowed or denied.
Possibly this can be done with packet tagging. We don't want to turn on all tracing for all packets just to test a single packet.
