Is it possible to reach many devices using just a domain or sbdomain?

hi everyone. This is the first time I write in this forum so let’s go to my question: Is it possible to reach as many devices connected in many and differents networks wifi using one single domain or subdomain?

Reading the docs I’m not sure if I add a domain or subdomain I can be able to reach just one device or many as I need to connect besides if I had this subdomain it means just having one tunnel…?? This is my doubt. Thank you so much in advance for your replies and the experience you can share me.

Greetings,

It is possible to reach multiple devices if they are connected to the same wifi. But it will only work for HTTP(S) connections. You need to use the multi-port forwarding feature.
