Hi.

I have TMG Server with 2 interface, 1 public 1 private

I configure the certificate and SSTP connection and everything seem to be working fine. 

I need to know how to add another authentication factor like OTP (I am using LinOTP).

Any help about this ?

Hi,

Please refer to the following article that decribes the steps for integrating DUO with TMG.

You could also ask a question in LinOTP forum to find more information.
