We have Peplink Balance Model 580 which we setup for L2TP VPN for remote users, we are using user name, password and a preshared key for login. My question is : is there a feature for Multifactor Authentication for this model? such as, sending a textcode to user phone, then the user receive this from the text to their phone and put this in, (besides their user name and password) before the connection can be established?
If this model does not have this feature, then is there any other model that has this feature?
