I tried searching for "ICMP" to see if ICMP-based relaying was mentioned somewhere, which used to enable NAT traversal without a third-party, but I couldn't find any matches. Has there been any consideration for this type of NAT traversal? (EDIT: Yes, libp2p/go-libp2p-autonat#100)

As an example implementation, with an explanation in the readme: https://github.com/samyk/pwnat

Nevermind, found libp2p/go-libp2p-autonat#100. However, the developer of pwnat, Sanyk, mentioned "You may also be interested in other P2P technologies like https://samy.pl/pwnat/ which I hope to be releasing a modernized version of soon around a new technique": samyk/slipstream#13 (comment)

Perhaps it may be worth contacting them?
