Nacreousyou can enable Connection Mirroring, so active f5 will sync tcp/udp packet sequence to standby f5.

I suggest only enable this during planned failover and make sure HA sync uses direct cabling between the 2 f5 devices

MustphaBassimHello Dear
Thnx for reply
More over the issue is the. server behaind F5 is accepted only one session otherwise the second session would be dropped and we think when F5 device make change in failover the previous node still open connection with server while the session must be killed and reestablish from new active node
So how it could done for that ?
