Hi folks,


I am a Mac User, and have little knowledge on IPFW.

I have a set up at home where my computer (with 2 ethernet cards and static IP adresses) serves Internet to my family's computers.

I have already a script that will run automatically at login and called from Cron at certain times, the purpose is to stop serving Internet to certain computers at a certain time.

I need help with a command that will block all trafic from and to an specific computer. But using the IP address is not enough. I wonder if I could specify the ethernet card's Mac Address within the IPFW command.

Is this possible?

Would someone be so kind to write me here an example line?

Thank you!
