Self-hosted VPN that can be accessed via browser extension
Currently I set up Tailscale in my Synology NAS and I can access selfhosted services on my phone using the Android app. I want to use some services in my work PC too but I'm blocked from installing any software. So my question is, is there any solution that allows me to connect to selfhosted VPN via browser extension? (Just like NordVPN, I can install the browser extension to use it and I don't need the Windows app.)
Yeah, that is the unfortunate reality. The better way is going through your IT department to get those extra things you need for work. If you are found out, and I am sure IT will eventually be able to, you will be in trouble.
I had the same problem as OP. My solution was to port forward to my server but then block connections from all IP addresses accept from my work, which I added to an allowlist.
It's working well so far, but I think the Cloudflare tunnel is the better option.
Most "VPN" browser extensions (if not all of them) aren't actually doing a VPN connection but just change the proxy setting in the browser. This is because as a browser extension they wouldn't have enough permissions/power to establish a real VPN connection.
So if you want to use a browser extension you have to run a proxy server, or as other said, just use cloudflared as running a proxy server attracts bots from all over the world
