VPN access restrictions between user

Hi, I’m using Pritunl VPN solutions but I need to have several organization under the same server. In each organization I will have mora than three users. I want to restrict the traffic between the users in different organization, I mean, the users from the organization 1 must’t have communication the users from the organization 2, but between the user in the same organization mut be communication.

Is it possible? How can I configure the Prtunl VPN to do that?

Many thanks in advance.

Traffic is controlled by servers and access is controlled by attaching organizations to the servers. Creating a server for each organization will prevent network access from users in other organizations.
