yYes it does!! Thank you, tested it and I could get two clients, each
behind their own NAT, to send and receive data via UDP.

Let me see if I understand exactly what’s happening here.
A public server is running udp01. That is always available and can be
contacted by anyone who initiates a connection.
When client A and B both connect to the server, your program connects them
together and that established the path that all further UDP traffic between
A and B will flow.
To ensure the path remains open, A and B need to contact the server once a
minute or so…
Is that essentially correct?
Now for my next question. Is it possible to do the same for tcp?
