Remote networking

Hey guys. I got something I'd like to get running but not sure the correct path.

I use a capture one pro for work and am looking for a way to set up a remote web server.

In capture one, a photo editing and teathering program. There is an option to set up a web server so someone on the same network can view the images that are coming in as someone shoots into the program.

I would like someone who is not on set to be able to access the webserver remotely.

What is the best way to achieve this. VPN?

Basically I would like a secure way to access a remote server.

Without! Having to have admin access to the routers/switches/dashboard... On either side of the connection

Thanks!
