Noob to IPFire, so bear with me.
I am running IPFire on a small development network and I am wanting to close the Firewall a bit. My philosophy is to shut everything down and then open up ports as they are needed.
I created a rule from the Red to Green that drops all protocols. I also created a rule that does the same from Green to Red. I’m thinking that everything should be blocked. However, I can still ping google.com from a client machine on the green network. What am I missing?
