Guide
A short overview of how to install Tailscale on your OpenMediaVault server and your phone, so openmediavault monitor can reach your server away from home without exposing the web interface to the internet.
Tailscale is a separate service from another company that links your own devices into a private network. openmediavault monitor does not need it, but it is a simple and safe way to reach a home server from outside. This is only an overview: the Tailscale and OpenMediaVault documentation have the details.
Sign up at tailscale.com with an account you already have, such as a Google, Microsoft or Apple account. The free personal plan is enough for a home setup.
OpenMediaVault runs on Debian, so follow the Linux installation steps of Tailscale on the server (over SSH or the console), then run the sign-in command it shows and open the link it prints to add the server to your Tailscale network.
Install the Tailscale app on your phone from the App Store or Google Play, sign in with the same account, and turn it on. Your phone and your server now see each other in the same private network.
In the Tailscale app or in its admin page, open the list of your devices and note the server’s address. It is a number that starts with 100, or a device name that Tailscale can resolve for you.
OpenMediaVault lets only administrators use its API. Create a dedicated administrator account with a strong password for the app in the OpenMediaVault web interface, under Users, instead of using your main one.
In openmediavault monitor, open Add server and enter the Tailscale address as the server address. Keep the protocol and the port of your OpenMediaVault web interface (HTTP and port 80 by default), enter the account and use Test connection before saving.
openmediavault monitor reaches the server only while Tailscale is connected on your phone. If the connection fails away from home, check that first.
You do not forward any port on your router and the OpenMediaVault web interface stays off the internet. Tailscale encrypts the traffic between your devices, even for a plain HTTP address.
If your server has a certificate that matches the address you use, prefer HTTPS. The app always validates certificates and never offers a trust-anyway option; a private certificate authority works once it is installed on your phone.
Tailscale is a separate product and openmediavault monitor is not affiliated with it. Read its own documentation for the exact steps on your system.
