      Dear All

      Behind the Pfsense we have a pbx (asterisk).
      The pbx hast to register on a public SIP-Trunk (TCP Port 5060).

      Usually everything works fine, but today our pbx could not register to the particular trunk.
      A reboot of the pfsense solved the issue.

      Does anybody have an idea how to troubleshoot this?
      Maybe it was related to a full state table?

      Thank you very much for your help and ideas.

      Best regards
      Fabian

        If the state table was full you should see some log entries to that effect.

        Do you have multiwan? Check for states on the wrong WAN if so.

        Do you run Snort/Suricata? In blocking mode?

        Did you see any firewall log entries relating to that connection?
