How do I turn off or revert Deep Packet Filter?

Because Deep Packet Filter (DPF) works purely through a DNS change, turning it off is simply a matter of undoing that change — there's no software to uninstall.

On a device (Windows, macOS, Android, iOS, Smart TV): go back to the same DNS settings screen you used during setup and switch DNS back to Automatic / Obtain DNS server address automatically, or remove the DPF addresses you entered. Save, and the device returns to your ISP's default DNS.

On a router: log into the router admin page, return to the DNS settings, clear the DPF addresses (or re-enable 'obtain DNS automatically from ISP'), and save. Every device behind the router reverts.

This is handy for troubleshooting too: if a particular app or device misbehaves, temporarily reverting DNS confirms whether DPF is involved.

Remember that reverting DNS is separate from cancelling your subscription — see our billing guidance for how to cancel. If you'd like help either way, our 24/7 UK support team is available.
