From haproxy-en.txt:

4.1.2) Per-server source address binding

As of versions 1.1.30 and 1.2.3, it is possible to specify a particular source to reach each server. This is useful when reaching backup servers from a different LAN, or to use an alternate path to reach the same server. It is also usable to provide source load-balancing for outgoing connections. Obviously, the same source address is used to send health-checks.

Example :

     # use a particular source to reach both servers
     listen http_proxy 0.0.0.0:65000
         mode http
         balance roundrobin
         server server01 192.168.1.1:80 source 192.168.2.13
         server server02 192.168.1.2:80 source 192.168.2.13

Example :

     # use a particular source to reach each servers
     listen http_proxy 0.0.0.0:65000
         mode http
         balance roundrobin
         server server01 192.168.1.1:80 source 192.168.1.1
         server server02 192.168.2.1:80 source 192.168.2.1
