I am running an ubuntu server with LAN ip on which I want to run openvpn server which will provide access to the LAN that ubuntu server is in. I will be opening a port on my router through which the ubuntu server will listen on. The network will be 192.168.0.0/255.255.0.0 The (eth0) ip of ubuntu server will be 192.168.9.10. The LAN gateway and dns server will be 192.168.0.1 (router). I have partially worked on it by using this guide. But the openvpn server fails to start, so something isn't right in my conf file. So what settings should I have in my openvpn conf file?
