When forwarding TCP sockets at OSI layer 4 with haproxy, it helps to
know the ephemeral port from which it sources each connection to the
backend. In this way, backend connections can be mapped to actual
client IP addresses by correlating backend service access logs with
haproxy logs.

for the default log-format documented here:
