  • Are you behind a CGNAT? Edit your question to provide that required clarity. We don’t need the serial number to your router.

  • If you search for CGNAT Bing and Google will do a better job explaining it than a comment limited to 500 characters. The issues you describe suggest you are indeed behind a CGNAT.

  • See How to check whether or not your ISP performs CGNAT and let us know the results.
