Basically I have hidden my server behind cloudflare. My server listens on port 80 and port 25461, and cloudflare only protects on certain ports, 80 being one of them.
But I have a lot of users, having access only to the old port, on their own ddns, to my original ip.
I can have them edit their dynamic dns to point at my new cloudflare domain, but their devices still use the old port.
I was thinking of setting up a man in the middle server, which forwards all queries to the URL, to the port 80 of my new server.
Ideally noip could just take the old incoming port, and forward to port 80. But it doesn't have this option.
So I want:
friends-url.ddns.net:24561 -> mycloudflare-server.com:80
