The topic of this chapter and the next is troubleshooting OpenVPN. This chapter will focus on troubleshooting OpenVPN misconfigurations, whereas the next chapter will focus on the all-too-common routing issues that occur when setting up a VPN.

The recipes in these chapters will therefore deal first with breaking the things. We will then provide the tools on how to find and solve the configuration errors. Some of the configuration directives used in this chapter have not been demonstrated before, so even if you are not interested in breaking things this chapter will still be insightful.
