Hi viksep You will need to configure the RADIUS server under [radius client] section then under [radius server auto] you will need to input the MX details to act as a client. if you are running this DUO proxy on the same machine as your RADIUS server then please change the port of the proxy from 1812 because that is what I am assuming you are using for your RADIUS server already so DUO proxy has to listen to a different port to authentication users. Please check my short video of the integration but note that I used direct integration with AD instead of RaDIUS but the concept is the same. https://www.youtube.com/watch?v=0kmNsun48Wc&t=20s
