Summary


In this chapter, we discussed how OpenVPN is installed and compiled, including some of the benefits of using software packages distributed by your operating system of choice. There are many places where a compilation or installation of OpenVPN can turn sour, and being cognizant of those will help you create a successful and maintainable VPN.

I think the hardest market today is the mobile market, primarily due to the lockdown of some application marketplaces and the restrictions placed on the environment and ecosystem. Being aware of these as well as some of the limitations of a given platform should set up correct and workable expectations.

In the next chapter, we dig into the log file, helping you identify problems and recognize some of the solutions indicated in the log messages. The previous chapters primarily covered the bases of how OpenVPN functions, how it's built, but only works on functional setups.
