Load Balance http and picking the correct gateway

  • I have two external interfaces WAN and DMZ and one internal LAN (
    WAN is a router port, has the IP and is the default gateway.
    DMZ is connected to a switch and has the IP
    The DMZ interface also has the virtual IP

    I want to load balance incoming traffic on to other servers in the LAN to, The traffic flows kindly from to and .6 - but the repsonse packets never reaches their destinies.

    I think I understand why: the default LAN GW is - so the traffic from and .6 reaches pfSense, but since the default gateway for the pfSense is, this will be used to send the response, but it should use - the incoming DMZ interface. I'm unsure how to solve this problem, anyone got a hint/tip?
