I just set up port forwarding (port 22) on my router (ip of 192.168.1.1). Now I can ssh into my server (ip of 192.168.1.7) remotely (from another internet connection) using its new static domain name I made with the www.noip.com service. However that new host name doesn't work when I'm on the local wifi of the server — when on local wifi, I can only ssh into it with
ssh firstname.lastname@example.org(as I could before I set up port forwarding). I wonder if a popup that appeared from the router before I clicked "submit" is relevant to not being able to ssh into the machine locally using the noip domain name. Screenshot from router is attached.
