I see a lot of people here uses some form of remote access tool (VPN/Tailscale) to access their home network when not at home. I can’t really do this because my phone (iOS) can only activate one VPN profile at a time, and I often need this for other stuff.
So I chose to expose most web based services on the public internet, behind Authelia. But I don’t know how safe this is.
What I’m really unsure are things like Vaultwarden: while the web interface is protected by Authelia (even use 2FA), its API address needs to be bypassed for direct access, otherwise the mobile APP won’t work. It feels like this is negative everything I’ve done so far.
My understanding is that it’s just not as secure. Any open port can be considered a potential way for a hacker to get in. Of course, that doesn’t mean it will 100% happen and you will get hacked, but at least in the case of Tailscale, it does it in a secure way that makes it so you don’t have those open ports. Basically, it’s not bad to just expose them to the internet, it’s just not as secure as using tools like Tailscale.
