Test Radius Challenge Response in NTRadPing

If you lack of the Challenge-Response (CR) VPN device, instead you can use NTRadPing to check or show DualShield Radius Server CR feature.

Basically, you need to create a radius logon procedure with two logon steps in DualShield.

With NTRadPing, in the second step, add the State attribute returned from the first step login. Please check the PDF version for the details.
