I don’t know what computer or OS you are using but the following is for Windows OS 7 SP1. I hope this image shows some of the information your are looking for and how to open and find it.
All that will show is the internal IP address for the mycloud!
Just google what is my ip and that is the IP address. For instance if you had instanced sabnzbd you’d access it remotely by typing your external ip followed by colon and the port you set it up on. For instance external ip:8080
Nope you are correct though what you will need to do is forward port 8080 to the mycloud in your routers settings. MY mycloud internal ip is 192.168.0.19 so I forward port 8080 to that and then I can access remotely.
