Got an Ipad last week. Got an Airport Express this week. Tried to setup a wifi network since 2 days trough ADSL modem. Mac Pro as no Airport Card. Ethernet port 1 goes to modem. Ethernet port 2 goes to Airport Express. Successfully configure Airport Express from MacPro. Can see network from Ipad but no internet connection. The question is: Am I loosing my time? Is there a way to setup so that I can get internet on Ipad?
Thanks.
Mac Pro, Mac OS X (10.6.7)

    Have you enabled internet sharing? (System Preferences > Sharing > Internet Sharing)

    Your settings should be:

    Share your connection from: Ethernet port 1

    To computers using: Ethernet port 2

    Did you restart your computer after applying the internet sharing settings?

    Did you reboot the express as well?

    AFAIK, your settings are where they should be, and it should be working.

    Actually now that I think about it, there is nothing on your network providing DHCP services, which is where your problem lies.

    You ISP is likely issuing you 1 IP address, that your Mac Pro is using. Since your ISP only provides 1 address, and the Mac Pro isn't a DHCP server, your Express isn't getting a valid IP address.

    If I were you, I would return the Express (you did mention that you just bought it, right?) and pick up an Extreme. This is a proper router that will handle DHCP. Your Extreme will plug into your modem, and then your Mac Pro will plug into your Extreme. Your iPad will connect wirelessly.

    Probably not the answer you're looking for, but it's the best way to do it AFAIK.

    Hey Bersan, I know it was a long time ago, but i'm trying to do exactly the same right now, but you did not post one information:

     

    1* Enable Internet sharing from Ethernet 1 (PPP) to Ethernet 2 (Airport Express).

    2* Manually configure IPv4 on Port 2 with address 192.168.2.1. Submask at 255.255.255.0 And the Router? What do i put???

    3* In Airport Utility create a wireless network. Setup connect via Ethernet.

    4* Share connection should be deactivate (bridge mode).

    5* Manually configure IPv4 in menu TCP/IP.

    IP:192.168.2.12

    Subnet mask:255.255.255.0

    Router:192.168.2.1

    DNS:192.168.2.1

     

    You did not explain how to fill the "router" field on the Ethernet 2 form...Screen Shot 2013-10-03 at 22.20.48.png

     

    Can you help me?

     

    Cheers!
