haproxy TCP load balancing, you only need to configure the "real servers" or "backends" behind the VIP (i.e., cluster IP). E.g.:
listen smtp 192.168.3.10:25 mode tcp balance roundrobin server smtp1 192.168.3.1:25 check server smtp1 192.168.3.2:25 check
lvs, I'd need to either:
- Set the
lvsmachine as the router to implement "NAT Routing"
lvsmachine and the backends have the VIP configured with some ARP mods on the backends
haproxy manage to do this without the more involved configuration? Am I misunderstanding or missing something fundamental here?
