Don’t bother with the DrayTek . They cannot keep up with virgins speeds . I’d recommend a Ubiquiti Edge Router X . Will cost you about £39+ Vat . There support is great if you need it and you can configure basics through a web ui but also have the benefit of the cli for the more advanced features . Plenty of guides on the net and YouTube.
