Description of Issue

I’m using Portmap.io to connect to internal devices from the internet. Port forwarding is not an option. This setup works well on other devices, and I have the Qnap connected as well. The trouble is the phone app is looking to my public ip address for a connection.

So, the question is can the ip address/url that phone app tries to connect to be changed?

Thanks in advance.
