    I am considering purchasing an rv042 for a client that needs WAN failover. I was concerned though as whether or not the router will actually be aware if the WAN port drops signal or does it just listen for ethernet traffic from the DSL modem ethernet port. ie does it use something along the lines of a keep-alive to test WAN connectivity. I understand the dual WANs are mostly for load-balancing (yes or no?) but I need the feature more for failover.

    :) Thanks for help in advance.

    There is a setting in the RV042 routers GUI for Network Service Detection

    quote from helpfile

    Network Service Detection
    This tool can detect the network connection status of ISP by pinging Default Gateway, ISP Host, Remote Host or DNS Lookup Host.
    Retry count: The count of ping. The default is 5.
    Retry timeout: The interval between two ping actions. The default is 30 seconds.
    When Fail:
    Generate the Error Condition in the System Log: The Router will generate the System Log when ping fail to inform users that the ISP connection is disconnected.
    Remove the Connection: This WAN Interface will be suspended when the network connection to ISP is not active. The traffic on this WAN will be dispatched to the other WAN port. Once ISP returns to connect, the traffic will be dispatched back.

    If you check this Detection box, you have to choose at lease one option from the following four items.
    Default Gateway: If you check this item, the Router will ping the default gateway first.
    ISP Host: After ping Default Gateway, the Router will ping ISP Host “Retry timeout" later. The ISP Host is provided by ISP.
    Remote Host: Enter the IP address of Remote Host that you’re going to ping.
    DNS Lookup Host: Enter the Host Name or Domain Name that you’re going to ping.

    kudos dude. that's about as definitive as it gets. have you used one of these boxes? If so have you been happy with the performance? Thanks for the assistance. My choice was between this and a Xincom appliance but I think I will go with the Linksys because of the easy VPN client.

    Pressley :D
