Hi @Jeetendra Sharma ,
From your post I'm also a little bit unclear about whether you are trying to allow the users or block the users. If users are being unintentionally blocked and you are permitting the access based on their private IP addresses, this is expected behavior since you cannot use private IP addresses for the named locations.
If the users are able to access when you have them blocked by the VPN, I would recommend confirming whether IPV6 is enabled on the VPN itself. p
To get more clarity, I would recommend sharing more details about which VPN you are using and your CA/Exclusion settings.
If the information helped you, please Accept the answer. This will help us and improve searchability for others in the community who may be researching similar questions.
