I was converting a company's VPNs to SSL, all worked ok except on a MS Surface Pro is an ARM64 based PC

The tablet has Win 11 Pro - 10.0.22631 Build 22631

When I try add an SSL VPN is says "Can't find VPPP adapter !!! - Not support VPN dialling type on current OS !!!"

The DrayTek Virtual PPP Adapter is missing from the Device Manager list and when I try to add it manually it doesn't accept the inf file.  Just doesn't add it.

Anyone had similar?

 

For further reference:

The 2FA feature on the Draytek routers only works with the Draytek Smart VPN client. Unfortunately the VPPP driver which is needed for the SSL VPN isn't ARM compatible (yet).  If you are installing on an ARM device in future and you see the Draytek VPPP driver then they've made that driver, if not, it likely still isn't there yet and you won't get the 2FA feature in the SSL VPN working.

I understand the same issue may happen on some Virtual Machines too but I haven't explored that.

In my case the customer was using a Microsoft Surface Pro to VPN to the office.
