Another Lemmy thread led me to thinking about getting a cheap VPS for my homelab. I’m double-NATted by my ISP, so I can’t do traditional port forwarding. I’d like to get a cheap VPS, install Tailscale on it, and access my homelab from anywhere without having to have Tailscale on every device I use (at work where I can’t install it, for example).
I found a cheap VPS company and the plan I was looking at gives 1000 GB bandwidth per month. Some of the things I want to access are media servers (Navidrome and Jellyfin). So if I set up the VPS with nothing but a reverse proxy and Tailscale, will all my Jellyfin traffic go through the VPS and count as bandwidth used?
This won’t work, your wan ip isn’t dynamic, it’s on the ISP NAT network and your resulting ip to public services is shared across many customers. CG-NAT.
It will with Tailscale though, as OP mentioned using. Tailscale clients reach out to DERP endpoints to create the routes they need to communicate with other clients. dNAT wouldn’t matter.
