Summary


Some of the most common configuration and deployment scenarios were covered in this chapter. In addition to identifying specific potential problems, we've demonstrated how to properly document your OpenVPN network and use diagrams for easier troubleshooting once problems occur. Preferably, identify the entire installation base and your configuration components prior to publishing your VPN to your customers or clients.

We have also helped to identify firewalls, IP address ranges, and operating system incompatibilities as potential problem areas.
