Bind HaProxy to the public IP when VIP is not set

[Raphyyy]

Hello,

Thanks for your work on this project, truly amazing.
I have 3 dedicated server in OVH (main French provider) each having a public IP and a private IP through a VLAN.

To ensure Load Balancing, there is no VIP available to purchase from this provider. However, I can configure an external OVH LoadBalancer to do the job. I want to configure this LB to reach my 3 HaProxy servers on their public adresses (the LB can't be in the VLAN).

The thing is that without referencing a vip_cluster HaProxy get binded to the private IP adresse. Is there a way to tell him in the configuration to bind on 0.0.0.0 instead ?

Also, I noticed that Postgres, Pgboncer and Patroni are binded on 0.0.0.0. Is there a way to make them listen only on the private address ?
