TCP hole punching for Bitcoin nodes behind home NATs?

The discussion revolves around the application of the hole-punching technique in scenarios where network address translation (NAT) is not used, such as with IPv6. It appears that connections are successfully established using this method even in environments where firewalls or configuration issues might prevent ports from being publicly opened. This observation suggests that hole punching can be effectively implemented in "No NAT" situations to facilitate connectivity. Accordingly, it would be beneficial to highlight these successful cases prominently in the results table by marking them in bold, thereby indicating their effectiveness under such conditions. This emphasis could help in understanding the broader applicability of hole punching across different network configurations.
