Omnia?

The Turris Omnia is quite a nice (although a little pricey) OpenWRT-based router from CZ.NIC. It provides a fairly powerful CPU, relatively unconstrained eMMC space, and quite a lot of hackability (some revisions even have GPIO ports to play with). It runs a modified version of OpenWRT, named TurrisOS.

The problem

A few years ago, I built a custom NAS for my storage needs, using a cheap Intel SoC (J1900 chipset) and a (much pricier) mini-ITX small form factor server tower. While I want it to be primarily a NAS, I wanted to run a few services on it, for example Nextcloud or Pymedusa. Of course, in these days it’s better to use HTTPS, and the process is both cheap and fast using Let’s Encrypt. I also wanted to use SNI with multiple subdomains (files.example.com, medusa.example.com, etc.) pointing to the same internal LAN IP (because some of the software I used is much harder to set up with subpaths of a single domain).
