Hi Haitham,
According to your description, you want to allow group 1 to only access RADIUS client 1,
group 2 only access RADIUS Client 2. We may achieve this goal by using conditions in network policy.
One of the network policy, in condition property, we may add
user group 1 and add client IP address of RADIUS client 1.
Another network policy, in condition property, we may add
user group 2 and client IP address of RADIUS client 2.
when we add serveral conditons in network policy, it needs to match all conditions to allow access, if any of the conditions couldn't be matched, access will be denied.
Best regards,
Anne he
