You should only have to run the script at startup ... IPs don't normally
change until the next time you start your PC.

You will want to use the ADSL section of "redhat-config-network" to make
WBEL startup and obtain an IP address if you are connecting directly to
the modem with your Ethernet Card and if you have PPPOE.

You can call the script from /etc/rc.d/rc.local ... and it will run
after the network has been started.

If you use redhat-config-network you should be able to add an ADSL
connection.
