Hi experts,
I'm looking for solutions regarding connectivity issue when a real server goes down.
Actually, I'm deploying Thunders for FWLB and tested for failover of Firewalls.
When a firewall goes down, connected clients are failed to communicate as expected.
I wonder the ACOS able to delete connections when health checking was failed.
Are there any options or need aFleX?

If your FW fails, the current sessions will be automatically dropped instantaneously once the firewall fails. The connections will have to be reinitiated from the users perspective.
With Firewall LB, ACOS can support L4 stateful failover and in order to achieve this feature, the firewalls have to also synchronize sessions across the FW pool.

Thank you for your reply.
I totally aggree with you, but if clients and servers are communicating with UDP and It's sent frequently from both side, then ACOS will not delete these connections I think.
