Linux firewalld config examples

Very helpful thank you. One thing I learned is that the zone which has your interface added to it will be the first zone of filtering applied to traffic. It took me a while to realize that. That kind of gave me an 'ah-ha' moment. I realized this when my public zone had the interface but I only had my ssh service allowed on the home zone. So the public zone was blocking ssh traffic before my home zone could allow it.

Something I didn't understand at first was the rich rule that you added. Since I use a non standard port for ssh I ended up modifying your rule to use a protocol/port instead of service. What I didn't realize is that this rule actually drops and logs the connections. I thought it was just going to log them.

Im not networking guy, ive been asked to open port on my box which is a jenkins node. I figured out with a website article but it didnt explain what each method do, so with you video a realize that públic zone is the default one, and active zone is defines when a source is added. Well still need to figure out what is the meaning when services is empty. Thanks máster, please continúe upload such great content
