I have a Cyberoam running 10.6.6.MR-2 (latest fw) and am attempting to setup a L2TP VPN authenticated with windows Network policy server (radius) installed on an active directory server.
I have the Cyberoam working with NPS (Cyberoam gives me green tick staus on test completion) I see successful authentication entries in the windows event log.
I have setup L2TP VPN and tested a windows 10 client authenticating againt the Cyberoam local accounts and this works OK.
However, when I get the windows 10 client to login using the credentials of a user on the active directory server I get the following:
I see no failed events in the windows event logs. Looks to me like its failed within the Cyberom, like its not trying to authenticate to windows radius (NPS)
Could you share the authentication settings set up on your Cyberoam, we have options to set for VPN ofr PPTP and L2TP. Make sure your Radius server is included.

The solution to this authentication issue can be the radius protocol as a link for remote access. Therefore, radius 2 factor authentication is possible with the generation of a one-time password using unique security parameters, and radius service , in turn, has support for this method of ensuring the reliability of user authorization.
