What are the Basics of Firewall Rules?

Firewalls play a very important role in IT security and in this video we discuss the basics of firewall rules

If you structure them in the proper way it will not only make it easier to maintain them, but it's less likely you'll accidentally allow access to something you didn't intend

We cover how creating sections can make rule handling easier to manage

How to set up different rules for access to internal servers and Internet servers

How to configure external facing rules and things to consider when self hosting your own computers on the Internet

We discuss how to manage rules for external firewalls

And also how stateful firewalls work and why guidance for bi-directional rules usually doesn't mean creating client AND server rules on your firewall
