Can I connect two Macs to share wireless internet access?

I'm sure this has been posted, but my search pulled up hundreds of threads. After I scanned the first 50, I decided to just post my question.

I have to wait a few days (at most) for my job to register my MAC address so that the new Mac Pro has access to the network/internet via ethernet. It does not have an Airport card or Bluetooth. While I am waiting, is there a way to connect the Mac Pro to my Powerbook (which has Wifi internet access) such that it can piggyback on the internet connection as a temporary solution?

Thanks much,
Amin

Put the ethernet cable between the macpro & powerbook / or a firewire cable.

On the powerbook, go into sytstem prefs / go into sharing

in Shaing / select internet.

Click share internet from Airport, and tick either ethernet or firewire and then click START..

That's it...

Won't the lack of a network-approved MAC address still inhibit this? The connection advice is sound, but it still has to get through the same network. Or does the sharing cancel that out?

^ It shouldn't.

If he already has a working wireless connection on a powerbook, sharing the internet access via firewire or ethernet should not be a problem on your macpro.

The network will only see the MBP's MAC address.

You'll be good to go with the above posted method.

You could also bring a router in and clone the MAC address of the MBP as well.

The first method is better because it is free though.

Wouldn't you need a cross-over cable to go from network card -> network card?

Thank you. I will try it as soon as the Mac Pro arrives (Fedex says Wednesday :) )

That is an appealing option and I don't mind paying a little for it. Is there a router that supports MAC address cloning but is not wireless? I don't want to get dinged for creating a wireless network at work, and I really have no use for wireless on my Mac Pro. It would simply enable me to get up and running faster without relying on a wireless connection.

Edit/Addendum - I think I found a good, cheap wired router to serve my needs - Linksys BEFSR41. Looks like it does MAC cloning, doesn't have wireless capabilities, and did I mention it's cheap?

Any Linksys router that I've ever used had MAC cloning avaiable.

Also, if you find a good deal on a wireless router (one that was cheaper then a wired router) you can always turn off the wireless.

I know it's dumb, but somehow I feel more secure getting one that can't do wireless :rolleyes: .

Just wanted to post back here that this is working (with FW). Thanks again MacRumorUser!

I am having an problem with this issue, and was wondering if someone out there can tell me where I'm going wrong.

I have a PowerMac G5 (Tiger) with an Airport card that connects to the internet via my Belkin router. That works no problem.

I have an iMac G3 (Panther) with no Airport, and would like to share the G5's Airport connection to the G3 over ethernet.

I connected the two with a standard, non-crossover ethernet cable; if I turn on file sharing on the G3, from the G5 I can see the G3's home directory and read/write files on there (to check if any network transport is possible between the two).

However, from the G3 I cannot connect to the internet. In the preferences I set it to assign address using DHCP, and it [seems to] gets one on the same network as the G5, but I can't even ping the G5, let alone use its internet connection.

Do I really need a crossover from G3->G5 (or a switch, which I can get cheaper than a crossover)? I thought G3->G3 needs crossover, but not G3->G5. And if a crossover is needed, how the hell does the file sharing work?!?!

I would have tried FireWire, but the G3 doesn't recognise its FireWire as a network adapter (is this a G3 hardware or Panther issue?).
