    Load Balancing Router Setup

    Hi Guys,

    I'm having an interesting problem setting up a load balancing router.
    Ive attached a picture try help explain the problem.

    We have 2 Cisco ADSL Routers supplied by our ISP.
    They each come with 5 assigned static IP Addresses.
    What I'm trying to do is plug a Load Balancing Router (LBR) into both of them and then use that to route traffic down the relevant line.
    I.e.

    - Internet Traffic down Router 1
    - Email traffic down Router 2

    etc... (Obviously it'll be more than that)

    Now the problem I'm having is that I can plug PC 1 & PC 2 into Router 1 or Router 2, assign them a static IP and everything works.

    However, as soon as I plug in the LBR into Router 1 and assign it one of the static IPs, PC 1's internet dies. The LBR and PC2's (via LBR) internet still work.

    Similarly with anyway I move them around, as soon as the LBR is assigned a static IP on one of the internet routers, all the other connections to that router lose their connection.

    I'm assuming its some setting on the LBR that clashing or causing routing errors for the router, but have no idea where to start?

    Any help would be greatly appreciated!

    Just a bit more info for you...

    As soon as the load balancing router is assigned one of the static IPs,
    any pcs assigned any of the other 4 static ips start getting IP conflict errors...

    Some more info, attached is a screenshot of the setup options for the wan links...

    I've crossed out some of the IP (nothing person, just don't want to advertise my currently wide open IP address )

    Its identical settings I would use if I were connecting a PC to the Internet Router.

    Do I need to put anything in the IP(s) in DMZ block?
    If so, what would I use? Surely that should be controlled by the Internet Router?
