An excellent introduction to Python where the instructor guides you through writing 5 Network applications. More than anything I think that this course opens the door for someone to go deeper into the subject and gives you some tangible examples as a stepping stone to make your own projects.
This was an excellent course that went into detail on the MikroTik Firewall and gave me a good understanding of some of the features that I was aware of but did not really understand. Specifically, the coverage of the Mangle and Raw firewall options was very useful and the description of the packet flow was critical to comprehending these elements. I am sure I will be referencing this course plenty in the future
