    most likely your client hub are setup as tunnel client and not tunnel servers.
    as such they are not listening on port 48003

    @Gene Howard That it's right, the server of the customer is Hub with client certificate. I thinked that the port 48003 was open when the tunnel it's established.
    So There is a way to monitor that the secondary hub is on Online, beyond to use (attach / post) on subscriber. Right now we have in monitoring the Ip adress of the server via ICMP, but only this.

    you could go to the hubs and just enable the tunnel server and not connect anything to it.
    this would cause the hub to listen on port 48003.
    You then should be able to use net_connect to test the connection to this but it is only as good as a ping would be as this will not mean that the tunnel is up and working.
