      Trying to determine what is causing these:

      Status -> System Logs -> Firewall

      Firewall -> Rules -> Lan, look like this.

          @stljonny Those are RST and ACK packets being blocked, as indicated by "TCP:RA", which can happen if two communicating machines aren't perfectly in sync. Those kinds of problems aren't really problems, and I'm willing to bet that other traffic passes without a problem. I've seen the same thing happen with traffic to some Google utility domains, but the functionality of the apps involved doesn't appear to be hampered.

            Yes, that's nothing to worry about. Just your internal clients ACKing a reset after the state has been closed by the firewall.
