Symptoms

FTP data connections do not honor LSN pool translation port ranges.

Impact

It is not possible to trace which subscriber initiated a data connection using LSN logs.

Conditions

This affects all FTP data connections in all LSN modes(NAPT and DNAT). The BIG-IP system chooses any valid ephemeral port instead of the range specified in the LSN pool

Workaround

None.

Fix Information

FTP data connections now honor LSN pool translation port ranges.
