Very informative and nice learning with this VPN technology course and thanks to Mr. David Bombal for the amazing course. Keep up and more courses to hear from you soon

David is extremely thorough! I play the videos at a slightly faster speed because I'll fall asleep at the default settings. However, he takes the time to repeat concepts to help make them stick which works great for me.

Me habría gustado que se explicara con mayor detalle las configuraciones y no enviar las configuraciones ya hechas.

This course is great and to the point. David covers all major tunnel types in his videos, and it's a very good refresher even if you are already familiar with tunnels.

Great course!!! The GNS3 portable project import file and config files provided for this course are great! Keep up the great work David.

Em vez de explicar a configuração da solução o autor usa ferramenta desenvolvida por ele e faz propaganda do seu site. Deveria fazer a configuração manual e explicar os conceitos envolvidos.
