CP Endpoint shows Access Denied and Duplicate Request and Response however NPS shows access granted

[simonsays]

Hi Everyone,

I am facing a strange issue while setting up the Windows NPS Radius Server with CheckPoint IPSec VPN .

after completing the configuration and trying to authenticate using the checkpoint endpoint client.

I see an "access denied error with incorrect username and password" at the client end and logs show "radius server not responding"

However, when I see the NPS Server logs in Event Viewer it shows ACCESS GRANTED

However, we are not able to set radius authentication for IPSec VPN

Using version CheckPoint GW 81.20

I followed this article and I was successful in setting up radius authentication on the web console itself

Have you verified with tcpdump that RADIUS packets are being received from the server?
