I run nginx proxy manager in a Synology VM. I don’t want to use the Synology reverse proxy partly because it gives away what it is, and also because it’s not very configurable as far as Locations go etc. The proxy manager gives me access to a couple services like Synology Drive without a VPN. But you need a VPN to get to DSM.
tailscale can be your new best friend, if you want it to. use it myself and couldnt be happier. pretty easy to setup compared to vanilla wireguard. its free too
Reverse proxy with MFA/SSO for anything that needs access externally (Plex/Overseerr/Home Assistant/DSM), VPN for anything that shouldn’b be accessed externally (Portainer/Unifi/SSH).
Use synology with tailscale. It’s perfect for this. I also have mine opened via a nginx reverse proxy and authelia 2FA, but this is not recommended for risk, and highly complex.
Does Tailscale work if your ISP doesn’t provide an externally addressable IP or blocks all incoming requests? I know someone that used a VPN with their old ISP but can’t with their new ISP because of this.
