  • Hallo and welcome to the UTM Community!

    Alone among the logs, the Firewall Live Log presents abbreviated information in a format easier to read quickly.  Usually, you can't troubleshoot without looking at the corresponding line from the full Firewall log file.  Please post one line corresponding to those above.

    Cheers - Bob
