FTP data connections do not honor LSN pool translation port ranges.
It is not possible to trace which subscriber initiated a data connection using LSN logs.
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
None.
FTP data connections now honor LSN pool translation port ranges.
