Synology regularly updates this list, but you can always add your own whitelist and blacklist under the web filter settings.

Network-level blocking is really useful for devices that cannot run ad-blocking browser plugins including iOS devices or smart TVs. Going forward, devices under this profile will stop seeing ads from known advertising domains and will not be tracked using known cookie sources. Here, select your No Ads filter and click save your settings. Go to profile settings (three dots in the right corner of the profile tab) and open the tab named Web Filter.

In case you don’t have any user profiles, create one under Profile > Profile > + (you can also create generic profiles that apply to all devices on your local network or guest network).

In the final step, you can add websites that you want to block, but feel free to skip this setting for now.

On the next screen, select Advertising as a category that you would like to block.

Give your web filter a unique name (e.g., No Ads) and as action select “Block”.

Under Safe Access, go to Profile > Web Filter > Add to create a new web filter rule.

Launch Package Center and install Safe Access.

Adding new Web Filter in SRM Step-by-step instructions: One of the key features of SRM is the ability to install additional apps using the Package Center and that is exactly how you can turn your router into an effective ad-blocking machine.

This router product line is built around the SRM operating system which is a fork of the popular DSM system used for NAS devices. Synology is known primarily as a leader in Network Attached Storage (NAS) space, but around 5 years ago they started offering high-end home routers as well. I have discovered a slightly simpler solution that is already built into every single Synology router. Although for an average user, the process of setting up these self-hosted apps and configuring your network to work with the new DNS server can be a little challenging. Blocking ads at the DNS level became very popular recently with Pi-Hole and AdGuard emerging as the two most popular solutions.
