How do you make a server that doesn’t require port forwarding or hamachi?

and it can connect people from different WiFis to the same server.

I’m new

You can not expect people to answer within 10 minutes.
You always need a specific port to send and recieve data, or maybe work with HTTP requests only. :stuck_out_tongue:
With Hamachi I guess you mean client hosted servers, get a dedicated server for that then.

I’m curious to why you can’t port forward? People act like it’s such a pain… but it’s so simple. Do you have another reason why port forwarding/paid dedicated server is not a solution?
