    I have a MPB running 10.6.3 We are receiving the cities wifi for which we have a outdoor receiver and an ethernet cable. I would like to share this internet connection with a Power mac G4 running 10.4.5
    for some reason i cannot share the connection. i have followed every tutorial i could find, it seems macs usually do not have problems connecting to each other.
    MBP:
    ethernet(internet connection)
    ip: 192.168.30.174
    router: 192.168.30.1
    DNS:192.168.30.1

    Airport:
    AirPort has the self-assigned IP address 169.254.73.195 and will not be able to connect to the Intern


    PMG4: when connected to MBP network
    Airport: TCP/IP DHCP
    IP: 169.254.14.21
    subnet mask: 255.255.0.0

    I hope that is enough and the right kind of info. I have no idea how to manually configure the G4.
    thank you be happy

    You can only share the Mac's on the same subnet unless you use special sharing applications like GoToMyPC.

    Your MBP is on subnet 192.168.xx.xx Your G4 "appears" to be on the cities wireless SSID subnet of 169.254.xx.xx. I'm guessing the Ethernet cable used for the MBP is connected to a router that translating the IP address from the city to a local subnet ...the 192.168.xx.xx Either provide a cable from the same router to your G4 -- or -- if you must use the Airport in the G4 then you will need to connect an inexpensive wireless bridge (Airport Express) connected to the router. You need to be on the same side of the subnet to connect with the built in capabilities of OS X.

    This is just a guess from what you described....Dan

    the G4 is not connected to the citi it is connected to the network that is coming from the MBP.
    MBP ariport utility is broadcasting, under advanced/TCPIP
    the IP 169.254.xxx.xxx
    subnet: 255.255.0.0

    so it seams that this is the fault of the airport network on the MBP side?

    Sorry....beyond what I can help? If you are using the MBP as a wireless access point or peer-to-peer wireless -- not sure how you did that. But, from what I know you still need both machines on the same subnet to share or enable Network Address Translation (NAT). Is there a way to "enable" NAT on the MBP Airport Utility? Out of my knowledge space!

    One more thing....just curious ... what is the SSID (network name) for the wireless connect on your G4?

    One problem is you have no DHCP server on your private network to hand out IP addresses. No guarantees but you could try this as a quick hack: manually configure the airport and G4 to have unique IP addresses in the range 192.168.30.xxx (use values between 0 or 255 for xxx), use netmask 255.255.255.0, and set the router/DNS as the mbp IP 192.168.30.174. AT least now you will have your devices on the same subnet. Also set the airport to work in "bridge mode".

    I have the mbp airport- set to ip:192.168.30.175 router 192.168.30.174
    but my ethernet ip is 192.168.30.174 (which is my internet connection)

    g4- ip: 192.168.30.176 router: 192.168.30.174
    do you think i should set the dns to ***.174 also? on both machines?

    I believe I was confused?

    Question: Do you simply want the G4 to have Internet access or do you need the MBP and the G4 to share files on a local network:

    If the answer is "G4 access to the Internet": follow this link:http://www.dummies.com/how-to/content/how-to-make-your-mac-a-wifi-access-point.html

    If the answer is "share files: follow this link: http://www.dummies.com/how-to/content/how-to-set-up-an-ad-hoc-wireless-network.html
