Hi Fatih, you could spoof the natping's source-ip so it would apear to come from the same host. I created a patch for that. It uses raw-sockets and works for me on linux. The patch is made against trunk. To use it, just set the udpping_from parameter of module nathelper. modparam("nathelper", "udpping_from" , "myhost:myport") Feedback on this would be welcome.
