manual vip assignment / rescheduling

hi again,

i want to build a vpn-"fullcluster" where i got 2 nodes and 2 vips
which get shared between them. if i set one nodes networkinterface
down. the other node sets the 2nd vip up.
now... when i put the first nodes nic up again it doesnt get another
vip. the second node keeps both vips. well thats nice behavior.
for example if one node is flapping he shouldnt get any new connections.

is there a way to tell wackamole that it should move one vip to a node ?
(yeah i know, i could stop and start wackamole on that node and the vips
get rescheduled)

also i would like to know what mature and balance intervals are for.


thanx in advance
 gerald


p.s.: i included my configs below
