What is normal practice for clients/players connecting UDP to the game-server ?
For example if we have 1000 concurrent players would you then all connect for example to UDP port 61234 - or do you seperate it so each client connect to its own UDP port on the server or is there a max ‘clients’ that is advised on a single UDP port ?
Ports are (mostly) an abstraction at this level, spreading connections across multiple ports doesn't have intrinsic performance benefits.
However, if you want multiple threads/processes to handle incoming messages, and you want messages from a given client to always arrive at the same thread/process, it can make sense to give each thread/process it's own port (though it's not really necessary, because SO_REUSEPORT exists).
