Remote Gateway Web Resources

I'm hosting an HTML camera feed (using Web Dev) on an Edge gateway and I want to provide that HTML to another gateway. Is there a way to do this with Ignition or is this something I need to setup a whole VPN setup for. Hypothetically I would just like to share that hosted HTML with the other gateway so they can use it as needed.

I was originally securing data transfers with MQTT and certs that we purchased. Low and behold we had our requirements changed and now they want the camera feeds potentially changing our whole setup.

Thoughts? Am I stuck setting up a VPN connection now to get this to work?
