Are open NAT connections maintained upon failover?
I heard someone say by default open NAT connections are maintained when a failover occurs in a HA pair..
I can't find any doc referencing this online.. Any insight?
Thanks!

since nat is stateless, i think we don't need mirroring.
i tested on 10.2.0. SSH and FTP survived after failing over. I didn't use mac masquerade.
BIG-IP Version 10.2.0 1707.0
