Hello.
I am working on setting up P2S in Azure VPN Gateway with Radius Authentication and want to use Okta Radius Agents for that.
I am able to do all the configs but having an issue where the Radius Access-Challenge is not getting receive by the Azure VPN Gateway.
Can you guide me if there is an issue with the Protocol or UDP MTU size ? Has anybody been able to have this setup working ?
Kind regards,
Mihai Stanciu

Hi @MihaiS.07567 (Customer) , Thank you for reaching out to the Okta Community!
I've been looking into this and was unable to locate any records of a successful integration with Azure VPN P2S and it's also not listed as one of the "common" integrations:
Common integrations:
https://help.okta.com/en-us/content/topics/integrations/integrations.htm
As for the protocol, I'm not seeing any overlap here, so that might be it.
Supported Protocols:
https://help.okta.com/en-us/content/topics/integrations/getting-started-about-radius.htm
https://learn.microsoft.com/en-us/azure/vpn-gateway/point-to-site-about
All that being said, I can't conclusively say if it's supported or not but I recommend checking the following articles to see if perhaps there's a "gotcha" that might apply to your use case.

If my answer helped, remember to mark it as best to increase its visibility for other members of the Okta Community who might have the same questions as you.
Hope my answer helps!
