Last Modified: Nov 07, 2022

Affected Product(s):
BIG-IP AFM, CGN(all modules)

Known Affected Versions:
13.1.0,,,,,,,,, 13.1.1,,, 14.0.0,,,,

Fixed In:

Opened: Jul 09, 2018

Severity: 3-Major


FW NAT / CGNAT modules query the subscriber ID using IPv6 address. If the query is done using the IPv6 mask, under some circumstances the query fails.


Logs contain UNKNOWN subscriber-id.


The network is using an IPv6 mask other than 128. Subscribers are created using the masked IP address as the key. If NAT module uses the complete IP address as the query key, the subscriber will not be found.


There is no workaround at this time.

Fix Information

Subscriber ID queries using IPv6 address are now returning the subscriber-id.
