No IP and port forwarding

I recently set up my first Mineos server, I have previously hosted servers directly from my windows machine but never as a Mineos plugin for Truenas. I was able to play in the server by entering the server name and IPV4 address, but when I created a No IP subdomain for it it does not work to connect. I have forwarded port 25565 on my routers GUI and still no dice. I want to be able to play with new people online and naturally I am hesitant to directly release my IP address, and I am not sure connecting externally using the Ipv4 address would even work, is there something I am overlooking?

edit: I somehow came to my senses and attached the no ip subdomain to the correct IP
