Opened: Jul 06, 2020
Severity: 3-Major


When a PEM profile is associated with a protocol that can create dynamic server-side listeners (such as FTP), and source-address-translation is also enabled on the virtual server, traffic on that flow (for example ftp-data) is not associated with the subscriber, and is therefore not counted or categorized.


Inaccurate subscriber traffic reporting and classification.


-- Listener configured with PEM and FTP profiles -- Some form of source address translation is enabled on the listener (for example, SNAT, Automap, SNAT Pool)
