The dyndns configuration should start on the dyndns page before the router can come. First, you need to register HERE at dyndns.com. I'm not showing this, I think you've already done this simple registration process. After logging in, click My Hosts. You can see where he is in the picture below. [img alt_text = 'dyndns option' description = ''] https:///wp-content/uploads/2017/01/dyn1.jpg [/ img] Then click Add New Hosname. I show you in the picture below. I covered the hosts I had already created with the red bars because they are not public. [img alt_text = 'dyndns settings' description = ''] https:///wp-content/uploads/2017/01/dyn2.jpg [/ img] Here are the last few steps required on the dyndns page. You can see the steps in the picture below, but I will describe them here as well. As a first step, enter a hostname that you want. Then choose a color-friendly ending for you in the picture now dyndns.ws, for example I usually choose dyndns.org. If you have it, click the blue link next to the arrow numbered 3. This will copy your current ip to the required small field. Then you have no choice but to activate the host. If you are complaining about a name match, choose another hostname and click activate again.
