Optimizing OpenVPN Throughput

In the previous post, I talked about OpenVPN TCP and UDP tunnels. In this post, I’m going to talk about optimizing the said tunnels to get the most out of them.

OpenVPN - TCP or UDP tunneling?

Spoiler alert: You most likely would want to use UDP tunneling!

An OpenVPN tunnel runs over IP and can encapsulates VPN traffic into either a UDP or a TCP connection. To understand the pros and cons of each, we first need to have an understanding of them both.
