From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Check if your ISP uses CGNAT for IPv4. If so, then you're out of luck and IPv4 pretty forwarding will never work.
See if your router has an external IP in the CGNAT 100.64.0.0/10 range.
If you have IPv6 you can add a firewall rule to your router to allow the forwarding port through and at least have other IPv6 peers connect.
