I am not familiar with OpenVPN but using with a subnet mask of defines your IP range as to By changing the subnet mask from to it will redefine your IP range to to allowing over 500 IP's, by default. Keep in mind doing so requires changing the subnet mask on all devices in the subnet; servers, printers, workstations and clients.
