Hi IPFire community:
I’ve been working with routers and switches for some time now. My only experience with firewalls is that you have to call some other team and ask them open up a rule for my traffic or check the logs to see if my traffic is denied.
I finally decided to go more hands on and start trying out some firewalls in my gns3 lab.
Doing IPFire basic configuration in gns3 was brilliantly simple. I only had one issue that cost some time and caused a bit of confusion. At first I didn’t quite grasp the significance of the step where we assign a MAC to a network. I finally understood the logic that the last byte in the MAC corresponds to the interface number. The install would have gone smoother if the step explicitly stated that you are choosing a MAC for eth0, eth1, etc.
