Server-side routing
This recipe will demonstrate how to set up server-side routing in client or server mode. With this setup, the OpenVPN client will be able to reach all the machines behind the OpenVPN server.
Compared to the previous recipe, this recipe contains extra settings that are often used in production environments including the use of linear addresses (topology subnet).
The configuration files used in this recipe are useful building blocks for other recipes throughout this book; therefore, they are named basic-udp-server.conf, basic-udp-client.conf, and so on.
Getting ready
Install OpenVPN 2.3.9 or higher on two computers. Make sure the computers are connected over a network. Set up the client and server certificates using the previous recipe. For this recipe, the server computer was running CentOS 6 Linux and OpenVPN 2.3.9 and the client was running Fedora 20 Linux and OpenVPN 2.3.9.
We use the following network layout here:
