Hello,
I need help on setting up a P2S configuration using Radius Auth but usign Okta Radius Agents.
I am unable to configure the Azure VPN Client or the Open VPN GUI to prompt the Second Factor message received from Okta MFA.
Do you have some working scenarios using Okta Radius Agents ?
Kind regards,
Mihai Stanciu

When you're using RADIUS authentication, there are multiple authentication instructions:
- certificate authentication,
- password authentication and
- other authentication methods and protocols. The VPN client configuration is different for each type of authentication.
Can you please let us know what authentication method are you using with RADIUS?
Cheers,
Kapil

2023-09-15T07:34:05.5366667+00:00 Hello. Okta Radius Support only PAP so i am using password Authentication.
It seems there is a problem with the protocol used by Azure VPN which uses EAPTLS and Okta Radius uses PAP. Is there any way to make them communicate in the same protocol?
If we can have a call that would be perfect.

2023-09-15T08:06:17.1533333+00:00 Currently, the supported Authentication Methods are
- EAPMSCHAPv2
- EAPTLS
I would suggest you to check if the third party can use any of the above authentication methods supported.

2023-09-22T07:55:57.2433333+00:00 As per this link https://learn.microsoft.com/en-us/azure/vpn-gateway/point-to-site-vpn-client-configuration-radius-other, Azure VPN uses PAP to communicate with Radius " If you have Point to Site VPN configured with RADIUS and OpenVPN, currently PAP is only authentication method supported between the gateway and RADIUS server" . I have the setup done, i get the sign in the problem is that azure vpn receives the Access-Challenge but doesn't correctly process it, and from the diagnostics logs i am not able to find out why, and microsoft support ticket i opened is not able to provide more information on the logs .
Since the Access-Challenge is received by the Azure VPN for sure is a problem with how that radius message is processed since the Client doesn't show the MFA challenge and Azure VPN authenticates the session.
Kind regards,
Mihai Stanciu

2023-09-25T05:31:56.8566667+00:00 To troubleshoot this issue further, I think we will need a specialized 1:1 session, where a support engineer can have a screen share session to pinpoint the issue.
If you have a support plan you may file a support ticket, else please do let us know, we will try and help you get a one-time free technical support.
