Also, using this file as another example: You could move the subnet out of the way to 10.8.255.0/24 if it gets in the way. etc/openvpn/nf is largely irrelevant as we do not normally use tcp connections.

You now overlap with /etc/openvpn/nf so you need to move the subnet there as well Care must be taken with expanding it so you don't overlap with the subnet in /etc/openvpn/nf. If the first parameter is not the base address, OpenVPN will fail to start. The first parameter must be the subnet base address and the second is the subnet mask. It is specified by the “server” line in /etc/openvpn/nf (and /etc/openvpn/nf).

If you want to increase this, you need to expand the subnet. This means that the maximum number of users is 62 or 63. Each user uses 4 IP's and the server uses 4. By default, OpenVPN is configured to use the 10.8.0.0/24 subnet.
