I have many servers in another internet data center. Can i use haproxy for load balance each website in them. Follow the documentation in the backend only using private IP how to use public IP like below. If it can’t have any app can do that? Thanks.

These are my settings:
haproxy.cfg

global
    daemon
    maxconn 256
    user        haproxy
    group       haproxy
    chroot      /var/lib/haproxy

defaults
    mode http
    timeout connect 5000ms
    timeout client 50000ms
    timeout server 50000ms

frontend http
    bind *:80
    default_backend servers

backend servers
    server server public ip?
    server server public ip?
    server server public ip?

    The IP address of the server can be any IP it can be reached on from the proxy. Typically it’s a private address on the same network as the server, but it doesn’t have to be – a public address of a server the other side of the world works, too.

    bind *:80
    default_backend servers

backend servers
