DrayTek Vigor

The Vigor range of routers from DrayTek are very good and I have used them since 2003.

If your router supports firmware 3.8.9.1 or later then you can use Teleworker VPN - IPsec XAuth - macOS Client to implement a secure VPN.

The Smart VPN SSL client software for macOS, iOS, iPadOS, Android and Windows is available from Software, this provides "app store" links, so is a good known source.

The UK is switching from copper phone lines to fibre by the end of 2025, the new service is called Digital Voice and is supported on a DrayTek Vigor, providing it has VoIP support. See How to Configure VoIP on Vigor Router – DrayTek FAQ for some help on setting this up.
