I'm trying to find out what the ip address is of my Base Station. I'm talking about the IP address that it's given by my LinkSys router - so I can forward some ports successfully.

Big Thanks in advance!!

    Normally use of a 3rd party router is
    You can go to your apple and then choose about this mac and then more info
    Now click on Network this will give you the assigned IP's for each computer assigned by and your base, including your base.

    Or when you connect to the airport, then open system preferences and then network, eather use the pop-up window at the top area or dubble click on Airport. Then go to the TCP/IP and you'll see it there.

    If you intend to use port forwarding, you should really not use DHCP assigned addresses. They can change on you. Fortunately, your Linksys router reserves some addresses for you so you can leave DHCP on for some computers but still assign static numbers for others and base stations.

    1. Open the Airport Admin Utility
    2. Click the Internet tab. I'm not sure, but you may be able to see the address you were looking for on this screen written in grey, but forget about that. You want more permanent addresses for what you are doing.
    3. Set configure to Manually and enter the following:
    IP address:
    Subnet Mask:
    Router Address:
    DNS Servers:

    The last number of the IP address can be anything from 2 to 100. Each router has to have a unique address. The Linksys should be starting with DHCP addresses at 101 and above.

    The router address on the Linksys has always been by default on every Linksys I have owned.

    Setting the router as the DNS server will get you the DNS addresses automatically like when you were using DHCP. You can alternatively look in System Profiler to find out what the DNS servers are and enter those numbers.

    You can use this on any wired computers you have that you want to have permanent addresses for port forwarding as well by using similar settings in Network preferences. You can use this for wireless, but your computer will attempt to connect to every wireless connection with the same settings so you have to set different "Locations" which need to be changed manually from the Apple menu.

    You are approaching this incorrectly. You need to configure your AirPort Extreme base station (AEBS) so that the option to distribute IP addresses is DISABLED.

    After you do that, your wireless computers will get IP addresses directly from your Linksys router. Then you configure the Linksys to forward the ports directly to the IP address assigned to the computer that is to receive that information.

    Yes, that's right, or when you try to play music through the AE's it only works for computers connected wirelessly. It's not necessary to have a bunch of small private networks and it just makes things more difficult to get working.

    This is the way I have mine set too, but I also disabled getting the address through DHCP and set it manually instead.

    If I do this, will it muck up new computers connecting to the wireless network?
