Ping/access webserver behind CGNAT? (lemmy.ml)

Hi guys! IN a bit of a rush, I installed a server on a place where I knew I'd have trouble reaching, as their router is behind CGNAT. I want now to start installing some VMs etc. At the moment all I have is a VM running Windows running Teamviewer for remote access (I know, I know). I have most of my services hosted on a local home server that runs rather well and has plenty of bandwidth. Among these, there's a PiVPN running on my home server that works rather well. Is there a way I could make that remote CGNAT server connect to my VPN and be reachable/pingable/show webpages locally?

Thanks!

Cloudflare tunnels can punch a hole through that. Get a reverse proxy setup for your apps and VMs, then create a cloudflare tunnel and you’re off to the races.

    Sorry, but I'm a bit lost with these specifics. I currently have a reverse proxy (nginx) publishing some of my apps running locally on my home server. Where should I put the reverse proxy? On the remote unreachable server, or? And how would the tunnel go?

    On the server that’s behind CGNAT, install Cloudflare tunnel. The tunnel will create an out going connection to Cloudflare, with an open socket; when you try to hit your specified subdomain, Cloudflare will receive your request, send it through the tunnel, and thus allow you to connect to your service.
