I have a number of VPN clients connecting to a Ubuntu 12.04 server (This was set up using Zentyal 3.0). I need to connect many more. I would like to be able to address the clients from the server by client hostname. The Openvpn server gives all the clients IPs in the 196.168.160.0/24 range. The Server running Openvpn has a 192.168.1.20 address. The DNS server is up and running but it does not resolve the host names of the clients on the VPN. How can I set up the DNS on the server so that I can ping, ssh etc., and connect to the Clients by hostname, from the server, rather than by IP address. Thanks, Jodel
