I'm new to Dynu and have never set up a DDNS. I've signed up for yearly DDNS services for $9.99/yr.

I've set up my DDNS name PrimeH2.com which is a register Domain name. I've also port forwarded my Websever using port 80 on my CUDY R700 Gigbit VPN Router.

However when I test it It doesn't access my web server.

I'm not sure if need to set up an alias for my web server on Dynu DDNS

DO you have any set by step configutation instructions or can you guide me setting this up?

Thank you
