Introduction

The recipes in this chapter will cover the deployment model of a single server with multiple remote clients capable of forwarding Ethernet traffic.

We will look at several common configurations, including bridging, the use of an external DHCP server, and also the use of the OpenVPN status file.

Please note that bridging should only be used as a last resort. Most of functionality provided by bridging can be achieved through other methods. Moreover, there are many disadvantages to using bridging, especially in terms of performance and security.
