YOu just need to set up /etc/sysconfig/network-scripts/ifcfg-ethX (where X is the number of the ethernet interface connected to the cable modem) to BOOTPROTO=dhcp
The ipchains configuration should not be referring to an IP address on the external interface, unless there are mroe than one IP addresses being assigned. If your brother's getting one IP, then just reference eth0. As to how to set up the firewall, I could give you a script, but it's for iptables...when I went to firewalling, I got a little bit of help from a friend, and we went right for iptables, skipping ipchains.
