Using
Ubuntu guide I successfully created a single OpenVPN server for many clients.
How can I create many OpenVPN servers on same machine for many clients each server has own its ca.crt and ca.key?
I need to use multi OpenVPN servers because I want to separate the users to groups each group can't see the other groups because recently I noticed that some users use port listeners to discover the working ports for that I want to use different master keys and certificates (I was separate users groups on same server by using different IP ranges and ports but because all of the users have same ca.crt and ca.key they can easily discover the other groups).
