I am doing LVS-NAT but using keepalived to handle the HA part in a
active-active setup. The primary server is a 192.168.1.1 and secondary
192.168.2.1. So when one fail's it grabs the failed IP, then ARP's to
take control of it. I have had FTP sessions continue with only a small
burp and no loss of data. It should work similar with heartbeat, but
things like FTP might lose connection.
