Task is following :
Hardware: BIG-IP VPR-C2400
Build: BIG-IP v11.6.1 (Build 2.107.338)
License: CGN
We use this device for CGNAT , after subscriber disconnected we need delete immediately all
its connections from connection table and also from PBA, because we have some suspicious
traffic after subscriber disconnect.
First off all i try do this with with magic iRules and tmsh, based on received Radius Account-disconnect meessages from NAS. 50-100 msg/sec are number discoonect messages in realtime received from NAS.
I try also play with timeouts of Virtual Server , TCP/UDP/FastL4 profile , PBA - unfortunately without results, some subscriber session stay alive until not closed from server side , often this is udp traffic.
If there are some other way please tell me.
Thanks.
