For this situation, we will use a VPN managed service from remote.it (this service creates a VPN between itself and your device, and let you access that device from its dynamic address)

STEP 1: Create a free developer account and install the remote.it service on your device by clicking add device option.

For raspberry pi just execute the below line

sudo apt update && sudo apt install -y connectd && sudo connectd_installer

STEP 2: Sign-in to the service using your credentials for remote.it on your terminal.

STEP 3: Select the Application (Port you want to open). Also, you can map any device in your LAN(ex. router homepage) to any application.

STEP 4: On the Web Console, click on DEVICE -> Device Name -> Service. Then from the window copy, the remote address and you are good to go.
