      Gentlemen:

      A heads up with respect to Suricata. I have Suricata the most current verison (Pfsense Package List) installed. It does not seem to run correctly with Pfsense 2.2.2. It installs, updates, a shows to be running but registers no alerts in a period of hours. We have a 100 M/s fiber connect so there is more than ample traffic. I reverted to Pfsense 2.2 and apparent normal operation returns.

      I have and additional question. When using Pfsense 2.2 and Suricata the following alerts are produced

      SURICATA STREAM ESTABLISHED retransmission packet before last ack

      Show I add these to a suppress list? What caused this repeating messages? Can I fix this issue?

      Thanks for any help

        That alert is from the Suricata stream processor.  You will the triggering rule and many others in the stream-events.rules file (look on the CATEGORIES tab and then select stream-events in the drop-down).  You can disable that rule and any others that you consider false positives or noise.  Suricata is extraordinarily chatty with these stream alerts.
