    Fix floating ips with external gateway

    If dnsmasq is configured to use an external gateway, then floating
    ips on other interfaces do not work properly. This is because
    outgoing traffic is no longer snatted to the floating ip.

    This patch fixes it by adding an ebtables rule to force traffic
    from ips that have a floating ip associated to route instead
    of bridge.

    Fixes bug 1096985
