Question about round robin

[Kevin]

Hello,



I am curious about simple round robin load balancing w/ PF. I see how simple
it is to setup within the FreeBSD configuration file, but have a fairly
simple question.

Does PF detect if one of the addresses in the "pool" is not responsive? Or
does it just blindly send traffic to all the addresses in the pool
regardless? Is there some sort of heartbeat functionality or status check
perhaps? Has anyone accomplished something along these lines? Load balancing
would be pretty useless if I couldn't take a server out of the pool without
having to re-configure PF every time.


Any comments are appreciated!


Thanks,


Kevin
