transparent Proxy on FreeBSD

[GARRISON, TRAVIS J.]

How can I configure haproxy to operate in transparent mode in FreeBSD. I have 
tried adding the line source 0.0.0.0 usesrc clientip to mu config but it states 
that I need to recompile with tproxy. I have tried adding the compile switch 
but it doesn't work. I have noticed that FreeBSD uses -DTPROXY. Is that 
basically the same thing? Thanks for any help

global
      maxconn 6000
      pidfile /var/run/haproxy.pid
      daemon
      nbproc 5

defaults
      mode http
      retries 3
      option redispatch
      maxconn 2000
      timeout connect 24h
      timeout client 24h
      timeout server 24h
      balance leastconn

listen PROXY 1.2.3.4:8080
      mode http
      cookie PROXY insert nocache indirect
      option forwardfor
      stats enable
      server PROXY1 1.2.3.4:8080 cookie PROXY check
      server PROXY1 1.2.3.4:8080 cookie PROXY check
      server PROXY1 1.2.3.4:8080 cookie PROXY check
      server PROXY1 1.2.3.4:8080 cookie PROXY check
      option redispatch

Thanks
