After many years of working and teaching FortiGate technology I decided to share my knowledge. I focus on troubleshooting. FortiGate – Troubleshooting Guide Quick Reference presents easy to understand techniques of troubleshooting on FortiGate platform. There are many debug command examples, which explain, how to read and understand the command output. The intention of the book is not to teach you how presented technologies work. I do not explain configuration examples but if you do not feel confident to perform troubleshooting effectively, the book is for you. https://www.amazon.com/dp/B087F95WFT
