Your router does not seem to have a public IP address, is it connected directly to the internet, or is there another router that gives you access to the internet?

The address you are using as wan is a private and cannot be used for DDNS.

tks. I put photos from drive.google that answer your question in a link to the topic post. I put new photo today: https://drive.google.com/drive/folders/1uMu0848ZknqB1p5Kp_y0S4S7Smf8-kYA?usp=sharing

Either you must run ddns on the ISP router, or use another method of detecting wan IP, like url.

Incidentally, my problem looks like this(???):

On my home router I use port forwarding normally. Smoothly.

Is there a solution for my case? Use proxy? DMZ? and How should I proceed?

9

As you can see in image02.1, I am using wwan and not wan. Is that correct? You said: "like url". Could you talk more about that? Where and How would I place this url?

10

There is no such evidence, your isp router is not behind cgnat and has a public routable IP.

No need to throw words you don't know what they mean.

It is under advanced settings tab of the ddns entry, ip address source option.

11

Not solved yet. You can see in image04 in link drive.google above

I continue with the same issues from the beginning and my etc/config/ddns not change. This is ok ?

12

Please paste here the output of uci export ddns
Make sure you are detecting public IP by url.
Also provide the monitoring and debugging output.

Your images show that you are under an undesirable double-NAT setup. If you can, I would try to avoid this, get a public IP on the OpenWrt router, and have this issue fixed.

What about these?

Sorry. I don't know yet How to do this. Can you help-me more to do this
(I can ping to 192.168.1.139 and neuberfran.dyndns.ws in Ubuntu 19.04. This desktop (with Ubuntu) stay in my residencial (isp router) network

I can't ping to 192.168.2.1 (OpenWrt router)

17

After a dyndns client runs successfully on any machine connected to your network which goes out on the same public IP, the name will be registered to that IP and it's ready to use. This can be as simple as clicking the update button on their web page, assuming your ISP doesn't change IP's frequently.

You don't necessarily have to run a client on the OpenWrt router.

Now to actually accept connections on the public IP you will need to forward port(s) in the main router going to the OpenWrt router and then in the OpenWrt router to the serving machine.
