I just got broadband, finally, because I live in the bloody countryside in Missouri.

To start, when I connect directly by Ethernet cable to my iMac I get the IP address The internet works just right.

Because I have two computers, the other a Linux/Windows box. I would like to use the wireless router to give both computers high speed internet.

The problem is that when I hook my gateway directly into my Airport Extreme, my iMac still receives the address. I get wireless internet just fine on my iMac but my PC box get nothing. In fact while my iMac get the address, my Airport get a address of and my PC get address It seems that the airport is giving itself a client address and iMac the ISP-given address.

Shouldn't my Airport get the and the clients recieve the series addresses? I don't know much about this stuff.

Here are the settings of my Airport and all client computers
Connect using Ethernet
Configure using DHCP
Distribute IP
Share single IP using DHCP & NAT
Using Addresses
Airport IP: <-- does this conflict with iMac router info below?
On the DHCP Client list it has no clients listed.

Configure IPv4
using DHCP
Router: <-- should this not be the router's IP and actually be like the PC has it?

Configure IP DHCP
QUOTE Thanks
