What does an unhandled packet log message in Traffic Monitor indicate?

An unhandled packet log message in Traffic Monitor signifies that the packet has been denied because it does not match any defined firewall policies. Firewalls use rules or policies to determine whether to allow or block traffic based on specific criteria such as the source and destination addresses, ports, and protocols. When a packet arrives at the firewall, it is analyzed against these configured rules.

If the packet does not align with any of these policy parameters, it is deemed unhandled and ultimately denied. This lack of matching indicates that the packet does not meet the conditions necessary to be permitted through the firewall, resulting in the creation of an unhandled packet log message. Such messages are essential for troubleshooting and understanding traffic flow, giving administrators insight into potential misconfigurations or the need for additional rules to accommodate specific types of traffic.
