It's been a long time since I had a domain and I can't seem to work out how to sort this out. I'm fairly confidant with local networking but this just has my brain muddled.
I bought a domain, X. My internet connection is a dynamic IP, so I set up a NO-IP dns address, Y. The local address of my server is Z.
I've set up a port forward rule in my router for port 18465 to Z.
I've pointed my dyn dns Y at Z.
I've pointed X at the DNS servers given by NO-IP and set CNAME "www" to Y.
I cannot connect to my public IP address, Y or X from outside the network.
Any pointers on what I've missed or what I can try are much appreciated.
