[WBEL-users] DHCP and firewall script

[Jean LEE]

Hello,

Thanks for your answers and links.
I don't need to use PPPoE but only DHCP so I do not have to create an xDSL
connection to make it working. I have only to configure my Ethernet card in
order to obtain an IP adress. I think your right : my IP adress do not
change until I restart the PC.
You said me that I can add the link to my script in /etc/rc.d/rc.local and
it will start it automatically after the network has been started. Is it a
security problem?
