"conflicts with the WAN IP address"
I just picked up a used AirPort Extreme N (Gigabit Ethernet) to replace my current non-Apple router, which has worked satisfactorily but lacks the ability to share disks--something I need. Using my G5 running 10.4.11, I downloaded AirPort Utility 5.4.2 to set up the new (to me) device, and did a factory reset just to clear everything out. I placed the AirPort in the network exactly where the old one had been--with its WAN port connected to the line supplied by my ISP (see below) and its three other ethernet ports connected to various clients. Then I ran into a problem:
Under the "Internet" icon of Airport Utility, I set it to Connect Using Ethernet, and Configure IPv4 using DHCP (My current router uses DHCP to provide IP addresss to both the wired and wireless devices on my network). The numbers below that are: IP address 192.168.1.12, subnet mask 255.255.255.0, and router address 192.168.1.1.
The first field of the line labeled "DNS Server(s)" defaults to 192.168.1.1, while the second field is empty, as are the fields Domain Name and DHCP Client ID. I left Ethernet WAN port on "Automatic" and put "Connection Sharing" on "Share a Public IP address," since I believe its combination of DHCP and NAT offer the best security.
The problem: When I click the "Update" button to confirm my settings, I get this message: "The DHCP range you have entered conflicts with the WAN IP address of your Apple wireless device."
Although I am unclear as to why the Internet Connection pane of the AirPort Utility lists "IP address" and "Router address" as two separate numbers (aren't they referring to the same device, the AirPort itself? How can it have two IP addresses?), I figured that I could play it safe and change the starting number to 192.168.1.13 to avoid the conflicts with 192.168.1.12.
But I still get the same error message when pressing "update." I tried changing the range to 192.168.1.50 - 192.168.1.60, and I still get the same error message. There seems to be no range that the utility will accept as non-conflicting with the "WAN IP address" of the Airport.
My ISP did not provide a visible modem as others in the past have done. The internet connection they left me simply comes out of a box on the back of the house that is connected by fiber optics to (presumably) a fiber optic line out in the street. However, this "supply line" has always worked fine with my non-Apple router and--after disconnecting the AirPort that had temporarily taken its place--is working right now as I throw this question to the forum.
Additional notes:
* Under the NAT tab, the box "Enable NAT Port Mapping Protocol" is checked, as it was by default) while "Enable default host at" is unchecked and blank.
* While I currently have wireless turned on in the AirPort, I haven't even tried wireless connectivity yet and want to make sure my wired connectivity is working first.
Thanks for any assistance.
