For those using a Synology NAS and looking to monitor DNS requests across devices, setting up a DNS Relay using Docker is a great option. This allows you to track DNS requests and apply different filtering policies based on VLANs.

Complete the following steps for an effective setup

1. Deploy the DNS Relay using Docker (as VMs won’t work on Synology NAS).
2. After deployment is complete, you can configure LAN subnets in the Relays section of the DNSFilter dashboard and assign them to different VLANs, allowing you to apply specific filtering policies for each subnet.

Check out our Docker Setup Guide for DNS Relay linked above for more detailed instructions.
