Using Mullvad WireGuard VPN with UniFi for Selective Domain Routing

Route only OSA-listed domains through a Mullvad WireGuard tunnel on UniFi. Pick any exit location—the example below uses Ireland.

1. Generate a Mullvad WireGuard configuration

  1. Visit the Mullvad WireGuard config generator and sign in.
  2. Set Operating system to Linux, then click Generate key.
  3. Choose an exit location that suits your needs (e.g. Ireland → ie-dub-wg-101).
  4. Under Tunnel traffic, select IPv4 only.
  5. Download the configuration file (for example mullvad-wg.conf) and store it safely.

2. Create a VPN client in UniFi

  1. Open the UniFi Network Controller.
  2. Navigate to Settings → VPN → VPN Client → Create VPN Client.
  3. Give the profile a descriptive name (for example OSA Bypass).
  4. Import the Mullvad configuration file you downloaded.
  5. Continue to the content configuration step—no additional changes are required here.

3. Add domain-based routing

  1. Within the VPN client wizard, choose Content Wizard → Domain.
  2. Select Add Multiple.
  3. Download the current OSA list in semicolon format (ideal for UniFi ingestion):

  4. Save the file locally (e.g. osa_domains.txt) and import it into the wizard.

Tip: you can narrow the download by adding &verdict=Censored or a specific category—see the Downloads page for query examples.

4. Apply and test

  1. Click Apply Changes to save the VPN client.
  2. Wait for UniFi to connect—confirm under Settings → VPN → VPN Client.
  3. Test a few domains from the list. They should now exit via the Mullvad tunnel, while everything else uses the normal WAN path.

5. Ongoing maintenance

  • The OSA list changes over time—re-download and re-import when you need refreshed data.
  • You can switch country at any time; just generate a new Mullvad config and re-import it.
  • Future work: automatic UniFi updates driven by the export API.
