Hello everyone,
I'm posting my message here hoping you understand my problem.
I'll explain, this procedure is done from my server locally.
So I comment, I open my webpage. I connect to my webpage at 127.0.0.1 (Local address) no issues + Ping (No issues).
Now, I access 192.168.1.183 from my browser, no issues + ping)
Up to this point, no issues. Now I enter my public address in the browser, 31.XX.XXX.XXX. Nothing happens (it used to work perfectly well for over a year!...) But I can ping my own public address (31.XX.XXX.XXX) WTF?..
Well, I'm on B-BOX version 2.0. (I didn't pay attention to the version, it changed by itself.)
Basically, I've reset my box several times. Hardware + Software... Firewall disabled... Anyway, nothing...
Any suggestions? I'm lost...

    Hello

    Now I'm using my public address on the browser, 31.XX.XXX.XXX. Nothing is happening
    It's normal, you cannot access your server with the public address...

    (it worked very well for over a year now!...)
    That's the most surprising part. It shouldn't be...

      Hello, thank you for your response. But I have a BBOX Pro sensation. And coincidentally, for exactly 3 days I have this issue, and I found this online;

      https://www.bbox-mag.fr/box/firmware/780-deploiement-du-firmware-9-2-38-pour-bbox-sensation-xdsl-et-ftth-sagem-3965b-modem-routeur/

      A firmware update 3 days ago! Isn't that great?... It's impossible to downgrade the version. In short, I can't do anything, my systems won't work anymore (I'm not saying more).
      The DMZ service doesn't work anymore, as well as NAT. Thank you Bouygues Telecom. I just have to contact them.

      Thank you for your response, and if we can access the server with the public address locally to see its site for example. The magic of the DMZ service.
      Have a nice day.

      Okay, I missed the DMZ box.

      But that might not prevent access from the outside..
      Have you tried?

      Hi,
      Yes, it works from the outside. I tested it with my phone using cellular data.
      It's only internally that I can no longer connect with my public IP. Very annoying... I’m eagerly waiting for a new update for my box. Otherwise, my programs won't work at all... I retested today, and nothing.

      Where is the problem of not being able to connect via the WAN IP address? For me, this IP should only be used for the outside.

      Everyone thinks that. It's true, yes. I completely agree with you. But if you configure the DMZ service on your router, you can also use your WAN IP at home!.. To connect to your site or applications.

    Hello,

    A little comment:

    It's normal, you can't access your server with the public address...

    This is called NAT Hairpinning, which is very commonly used, and some routers have it built-in (especially with the "DMZ" feature).

    Using a registry "compactor" on top of a registry "cleaner" would be equivalent to rinsing your throat with a swig of Jack Daniels after swallowing a pint of snake oil....

      The term "Nat on a stick" is also used to describe this process. ;)
