What is everyone else using for VPN solutions and what are the trade offs?
I want a VPN to access all my personal devices and use services like Syncthing. I use it on my phone so it can’t use ungodly amounts of idle data.
I looked at Netbird but found the idle data usage almost 1GB per few days using JetBird with Lazy connections. I tried the default app but it makes me SSO login every day or two, it wouldn’t stay connected, and it still used a reasonable amount of idle data.
I looked at Tailscale but I’m not going to lock access to all my devices behind a Google account login or some other third party service login for no reason. It seems like hosting my own auth server is too much additional risk as well. I tried self hosting headscale which worked well except that I have no decent front end to easily add devices. I have to log into a terminal, then execute docker commands which was a huge pain in the ass. I didn’t even touch on any of the firewalling or routing that can be done because it was so much more complex in headscale then in a web interface. I tried hosting two or three headscale front ends but couldn’t get one working that supported most of the available feature set. Usually I was given generic connection errors with no clear way to diagnose or clear troubleshooting steps so after a few hours I moved on.
Sounds like you’re talking about a Mesh VPN.
Syncthing doesn’t need a VPN to function - in fact you’re better off not using a VPN as it’s own rules will see the VPN as a LAN connection and sync data across it when your Syncthing rules exclude using your data connection. Maybe that’s what you saw with Netbird’s data usage. I’d be really surprised if Netbird itself used any significant data.
I have about 20 sync jobs per phone - some are allowed to use cell data (photos), others aren’t. When I enable Tailscale on my phone, Syncthing will try to sync all the jobs because it sees the VPN as a LAN.
I run rooted and use a firewall and block VPN there for Syncthing to prevent this.
