Two RADIUS server for VPN authentication

Hi,

I want to use Cisco ISE as a central point of authentication for users, so I need to configure check point in such a way that it sends two radius request to ISE. First request should have username/password - ISE will send it to the AD for the 1st authentication. The second request should have username/token so it is sent to Duo for 2nd authentication.

I believe the only way how to do it is to leverage multiple login options so the VPN client presents two windows to users. I tried to setup two authentication factors on a gateway but it said that only one RADIUS server is allowed. Is it possible to somehow bypass this rule?

 

thank you

Radius is based on challenge response, so configuring it one time is enough.

- First you enter username/password

- Check Point sends both to radius server (ISE)

- ISE matches username/password and asks for a challenge because of 2nd factor

- Check Point receives challenge and requests input of token

- Token is sent to ISE which issues a access-accept back if it is matching

Hi Norbert,

I am not quite sure whether I can configure ISE to request check point for the 2nd factor if 1st factor is successful.
