Thanks for answer but both solutions cannot help as:
- The route table already have a route to the second IP as it is
floating IP which is bound to the host. So traffic coming to the floating
IP as to get back through the floating IP
- Postfix is screen-walled by HAProxy and cannot be adapted.
- Monit would have to attack floating IP range from static IP instead
from any locally bound floating IP
- It would trigger a external network overhead instead of staying at
the host network stack level but we don't care here.
