Hello everyone.

Well, I wanted to ask some questions about IPTables. Now, I glanced over the PET's on this domain and I noticed that there were a few PET's on OpenBSD and PF. Which is cool as I have worked with OpenBSD and PF and love it.
However, I just wanted to learn a Linux firewall so increase my knowledge.

Basically, my first question is how do you setup your interface/rules when you are connected via a cable modem and receive a IP via DHCP server?

I just want to see what I have to specify to let my interfaces know to get its IP via DHCP.

Anyone have an example or two?

Thank you,
