      Curious why one of my lan clients would be blocked like this… Only to this address.  no rules to forbid...  1.2.3 latest.  Everything else works from machine.

      I believe its just Google trying to do lookups from this particular machine (not mine to diagnose) but just wondering...

        I'm guessing maybe it is a retransmitted FIN segment.  Since the original FIN got through, the connection has been removed from the state table, so seeing a FIN segment is illegal and pfsense drops it (this is just a guess, mind you.)
