I am running a 2 node lvs cluster using lvs-nat and running on debian etch.  I 
am using heartbeat to provide my high availability.  I am load balancing 
incoming smtp and its working great.

I have posted previously about this and thought I had it solved.  My setup is 
active/passive and I am trying to sync the connection states between the 2 
servers.  It syncs up fine from the primary to the backup, so when failover 
occurs it works and the connection states and sync'ed up with the backup 
server.  But when I try to fallback (manually) and can't get it to sync the 
connections from backup to primary.  I am not sure how I can deal with this.  
The only thing I can think of is to create a separate set of commands on the 
backup server and primary to sync the connection state from backup to primary, 
and then just manually start those commands prior to fallback.  Once the 
primary is back in business then stop the 2nd commands and start up the 
original commands to sync the connections from primary to backup.
This is the page I got my commands from

Any help is appreciated.   Everything else is working, this is just me being to 
nit picky.
