Hmmm, he doesn't need to select DHCP (or maybe he already has) since the
interface (eth0) already has an assigned IP address on 192.168.1.0
network (192.168.1.4).  Can you ping the router's IP address ('ping
192.168.1.1')?  If so then you need to look at your router's external
IP address (the one that is actually visible to the Internet via your
ISP provided IP address).
