DUO MFA for Clientless VPN

L2 Linker

Hi. Did anyone know if it is possible to use MFA (for examlpe with DUO) for Global Protect Clientless VPN?


Best regards, Markus

Yes it is possible, You just need to setup the authentication method, Device ->Server Profiles,  first then add it to your VPN config.


Hope that helps.

Hi. I already tried that, but I got the response bad username or password only one or two seconds after I entered my credentials. In the authentication log I can see that both authentications work well.


Best regards, Markus


In the past I have created two Server profiles for the ones I wanted to use and then used one for the gateway and the other for the portal authentication. I have yet to play with the v8.0.x feature of MultiFactor Authentication to see how that works.





Hi all,


Same here, I experience the same issue as Markus. I try to use 2FA with DUO on Clientless GP. I get a DUO Push Notification to my phone, but in the flash of a second, the GP Portal website directly goes to Wrong password.


I am using 8.1.0 PAN-OS


If you find out something, lets share!

I've also tried this and had the same result; Duo notification followed by GP invalid password message. From my discussions with Palo, it would seem that native Duo 2FA isn't supported yet for GP.


You can work around it in a way though by utilising an external radius server to perform the 2FA part of the authentication, rather than the native method.
