Aha, I now see why, ip_vs_bind_dest assigns the
forwarding mode from real server, not from SYNC messages.
As you have LOCALNODE when S2 is slave, the DR mode from
SYNC message is not used, that is why after failover the
S2 connections work and are not reset. So, at least, we have
explanation for all things that happen. If you run slave
without any rules the connection will use the mode from
master and you will see packet loop.
