Current setup: UTM with users who VPN in using the native Windows 10 client via L2TP. Users are authenticated through UTM, RADIUS connection to Windows server.
Need 2FA solution.
Already tried:
- Duo - doesn't work. We have their proxy installed. It works fine for WebAdmin, but for L2TP it fails as the Duo proxy isn't able to handle the MS-CHAPv2 format.
- OTP function in UTM - doesn't work. We tried some Feitian tokens and it doesn't seem to work. We tried appending the nonce after the password, we tried password - comma - nonce. It doesn't work and the connection fails.
We need to use L2TP with native Windows VPN client because roaming profiles and folder redirection is in use, and the users are synchronizing/authenticating with AD before Windows login occurs.
Any suggestions appreciated.
