It doesn't work as I would want.
I spent quiet a long time on pf docs and suppose this setting should keep the real server IP during this timeout setting. I am not sure i understood , but a round robin translation rule and a sticky setting should keep sources IP to the same destination server in the next connection…
I can see the src nodes (and my own IP) in the pfs statistics, but I get several ones with my own IP to different web real server (behind the carp VIP) and I still get loadbalanced on the 3 www when the states are expired (before the 4 minutes defined). My max src nodes are under the 10000 limit - 2000 - so I think this is something else.
I will continue to read pf howtos etc
Any piece of advice would be appreciated,
