In my experience both iroh and libp2p fail most of the time and need to revert to relays. The joys of cgnat.

Id urge you to try both out again and verify results. The comment is fairly dismissive, yet both do work even behind a cgnat (albeit not under all conditions). If you do find a general solution to the problem, please do share.

I have the same experience with libp2p. Something is always broken. Last time it was mDNS.
