How to Install Technitium on Your Synology NAS

Technitium DNS Server is an open source authoritative as well as recursive DNS server that can be used for self hosting a DNS server for privacy & security. It works out-of-the-box with no or minimal configuration and provides a user friendly web console accessible using any modern web browser. Nobody really bothers about domain name resolution since it works automatically behind the scenes and is complex to understand. Most computer software use the operating system’s DNS resolver that usually query the configured ISP’s DNS server using the UDP protocol. In this step by step guide I will show you how to install Technitium on your Synology NAS using Docker & Portainer.

šŸ’”Note:Ā This guide works perfectly with the latest version of Technitium v14.2

InstallĀ Portainer using my step by step guide. If you already have Portainer installed on your Synology NAS, skip this STEP. Attention: Make sure you have installed the latest Portainer version.

  • STEP 3

āš ļøMandatory STEP: If you have already installed the PiHole or Adguard container, remember to disable or simply stop them to be able to use Technitium since Technitium uses the same default port 53 as PiHole and Adguard.

  • STEP 4

Go toĀ File Station and open the docker folder. Inside the docker folder, create one new folder and name it technitium. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

Iā€™ve been very honest about this aspect of my work since the beginning: I donā€™t run any ADS, I donā€™t require subscriptions, paid or otherwise, I donā€™t collect IPs, emails, and I donā€™t have any referral links from Amazon or other merchants. I also donā€™t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. Itā€™s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
