Hi, I am a newby but a need to know something I think is quite complex.
I need to setup the firewall IPTABLES on CentOS (Readhat).
I wanted to know:
1) can I setup it from the conf file ? I see on the newsgroup that normally
people use the command bar by typing the commands, but I would prefere to do
it on the configuration file.

2) I have 2 ethernet: on eth1 I have the wan, on eth0 the lan. I wanted to
allow to acces FROM the LAN only to a computer with MAC ADRESS xxxxxx. Could
you write me kindly the command I have to put in the conf file ? Or better
if you could post a small example... would be great !!!

Thanks :-)
