Load balancer and HAproxy

[braxton]

What is the difference between the load balancer option on pfsense and the package haproxy?

[Itwerx]

Load balancer just looks at ports and IPs, not packet content.  This makes LoadBalancer more appropriate sometimes, (esp. for non-HTTP traffic) but completely unworkable at other times, e.g. if HTTP headers need to be rewritten on the fly, (which HAproxy does).
