I have a server that hosts virtual clients (KVM). My virtual network uses the IP range 192.168.122.0/16, which means I want to communicate with addresses in the range 192.168.x.y.

Now I am installing OpenVPN and want to configure it so that VPN clients receive IP addresses in the range 192.168.123.x/16.

I want my VPN clients to have access to my virtual network (192.168.122.x) and to the internet.

How should I structure the /etc/openvpn/server.conf file and the firewall rules?
