2 bugs in Outbound Multi-WAN Load Balancing with Gateway Groups



  • I've used Gateway Group for "Outbound Multi-WAN Load Balancing" according to http://forum.pfsense.org/index.php/topic,10407.0.html

    1. first bug:
      I have 2 uneven ADSL links: 128kbps + 512kbps.
      So I need to create 4 gateways with identical IP, but get error:
          * The gateway IP address "xxx" already exists

    2. second bug:
      I created 2 gateways with different gateways IPs but with identical monitor IP and get error:
          * The monitor IP address "yyy" is already in use. You must choose a different monitor IP.
      But I really need to check links against the same public IP!

  • Neither one of those are bugs. You can't use the same monitor IP on multiple gateways, and you can't use the same gateway IP on multiple interfaces.



  • Oh, on the first, we do need to bring back a way to accommodate unequal balancing.

  • @cmb:

    You can't use the same monitor IP on multiple gateways.

    Why not?
    I have both gateways to the same ISP and I want use his main router as monitor IP on both gateways…



  • Because of how routing works.
    This is not a pfSense specific problem.
    Behind the scene a static route for each monitor IP to it's respective gateway is created.
    You cannot create a static route for the same IP to multiple gateways.
