Hi Greame, appreciate the response. I've tried setting it to 1. Unfortunately
I'm getting the same behavior.
Single client sshing into 172.20.5.7 gets the same real server every time.
My config, maybe someone will see an error on my part.

Do you have ‘persistence_timeout’ set or not in your keepalived configuration?
If not, it defaults to 6 minutes - which means if you open a new connection
within that time of any other traffic traversing the director, you’ll get sent
to the same realserver.
If you set it to something short(ish) you should get the behaviour you require.
I think.
Graeme
