[TriLUG] iptables vs. ipchains

[Greg Brown]

Sorry if this has been covered recently, I'm still going through all my old 
digests.

I have two questions:

1.  I am curently using ipchains, is there a good reason to make the switch 
to iptables?

2. Does either ipchains or iptables have the ability to filter traffic on an 
interface based on MAC address?

I guess I have three questions.

3.  Is there a good iptables tutorial on-line for people who currently use 
ipchains?
