OpenVpn ip numbers

[jodel]

Hi,
I have linux only clients connecting to a linux server all using openvpn. I am using 192.168.160.0/24 addresses for the clients. I am trying to allocate fixed ip numbers to each client.
Does each connection need 2 ips i.e.
192.168.1.2 and 192.168.1.3
192.168.1.4 and 192.168.1.5
192.168.1.6 and 192.168.1.7
....... etc
i.e I can connect a max of approx 126 clients ?

Or is one IP sufficient for each client?

When I look at my server-ipp.txt file it says that .2 and .3 are allocated to the first connection and that .4 is allocated to the second connection.

Thanks
Jodel
