UDP hole punching question #23

Closed andrewarrow closed 6 years ago

andrewarrow commented 7 years ago

thanks for this repo, just what I was looking for.

Question on UDP hole punching: is this something the big peer networks do reliable to the point they don't have to send people to https://portforward.com or do the majority of peer to peer networks not use UDP hole punching because it isn't 100% reliable and having the user go into their router and make a real open port is always a more reliable solution?

Your question is incredibly convoluted and very long, so it's not clear what you are asking for. It's best if you break this down into multiple questions.
