static IP address more that in ipp.txt exactly by 2

I have a strange behavior that i could't explain.

I have deployed open VPN server on Ubuntu 16.04.

For some clients I need to have static ip addresses so I made the ipp.txt file with the following content:

user1,10.8.0.4
user2,10.8.0.8

But the strange thing - that when user2 is connected it gets ip address 10.8.0.10 (always, it is not a random ip address, so ipp.txt is working)
So I tried to play around with ipp.txt, and learned that the client gets ip adress saved in ipp.txt + 2 for instance:

user2,10.8.0.8 + 2 = 10.8.0.10

Even if change ipp.txt the logic stays the same, openvpn server always magically adds two....
I have some unsolved mystery here, so I am curious - why is it that? How can this be explained?

i think thats probably because you are not using topology subnet, net30 is the default as far as i know

It seems so.. But why do the windows clients need to have their own small subnets/30?
If I set topology to subnet, will it break compatibility with my existing windows machines (they are using the latest version available for downloading on the official website)?

net30 is not necessary any more for Windows.

We need your server config file...
