Description

A flow with IPv4 IP in IP traffic won't handle this tunneling case properly.
This leads to potential malicious traffic not triggering alerts, as well as other
inaccuracies in the logs.

Check if this case is also missing in other scenarios.

Waiting to see if the pcap shared can be added to a public SV test.
