    Hi all,
    If I have two internet service providers, and I intend to setup a linux box (with 3 network cards
    called internal_nic, WAN_nic01 and WAN_nic02) to balance the lad between these 2 ISP.
    How can I do that?

    Have anyone done that before?

    Please advise me the steps and the services neeeds to be installed.

    Kernel patches needed for load balancing

    Just a note that this solution works fine for a single machine, but if you are using load balancing on a gateway/router that is NAT-ing multiple machines, then you will need to build a custom kernel using the patches located at Otherwise you will experience packet loss and hung connections from the NAT-ed machines.
