XPEnology gave me Synology's operating system on my own hardware, and now I can't justify the official price

My makeshift setup does everything a real Synology does

Synology felt like an appliance until I built a custom NAS with TrueNAS and realized what I was missing

Synology is fantastic, but a custom NAS can be much better.

Free NAS distros beat Synology's price, and the performance gap doesn't justify the markup

You can do better either way.

What is Pi-hole and how does it work on a Synology NAS?

Pi-hole is a DNS-level ad blocker that filters ad and tracker domains before they reach your devices. On a Synology NAS, it runs as a Docker container in Container Manager. Your router points DNS queries to the Pi-hole IP, and Pi-hole decides whether to allow or block each request based on its blocklists.

Why can’t my Synology NAS reach Pi-hole on the macvlan IP?

Macvlan is a known limitation — the host machine (in this case, the NAS) cannot communicate with containers on a macvlan network. The Docker Compose file in this guide creates a second bridge network (192.168.100.2) specifically so the NAS can reach Pi-hole. Use that IP if you want the NAS itself to use Pi-hole for DNS.
