Short answer
Log in at myrouter.local (or 192.168.1.1) or open the Linksys app, go to Connectivity › Internet Settings › Edit (or Advanced Settings › Internet Settings), set DNS 1 to your Sheepdog Filter address, leave DNS 2 empty, and save. Then turn IPv6 off.
Before you start
In your Sheepdog Filter dashboard, open Devices › + Protect something › Everyone at home and copy your DNS address.
Step 1: Find the DNS setting
- On a computer: go to myrouter.local (or 192.168.1.1) and log in. Open Connectivity › Internet Settings and click Edit next to the connection type.
- In the Linksys app: tap the menu › Advanced Settings › Internet Settings.
Step 2: Fill in the boxes
- Static DNS 1: paste your Sheepdog Filter address.
- Static DNS 2: leave empty. Never add Google (8.8.8.8) or your internet company's address, or devices will slip around the filter.
Click Apply or Save.
Step 3: Turn IPv6 off
Under Connectivity › Internet Settings › IPv6, uncheck Automatic or disable IPv6, and save. This stops devices quietly going around the filter.
