Using your MacBook Pro as a Router For the Xbox 360

Not sure how many of you guys have 360s, but I've written up a guide to use your MBP as a connection point for the 360. Basically it involves sharing your Airport with the Ethernet port. Here goes.

Welcome! I recently purchased a MacBook Pro and did not feel like shelling out 130 dollars for the
360s Wireless Adapter.

Thus I set out to find a solution and it was my shiny new mac that came to the rescue.
I'm positive this can be done in Windows, but I've not taken the time (yet) to test it.
I think it's very simple to follow, but I do recommend that only those with patience and a will to learn attempt the setup.
Also if you don't know how to reset your router, I wouldn't recommend it either. But for the rest, on we go.


You will need these things for this adventure:
Broadband Internet Access
1 Xbox 360
1 CrossOver Cat 5 (NOT Patch, so NOT the one that came with the 360)
1 Macbook Pro (the regular Macbook may work, I haven't tested it)
1 Router with wireless and wired connections or 2 Routers linked together, one wired, one wireless.

Plug the cross cable into the ethernet port on the mac and the ethernet port on the Xbox 360. Turn both on.
Go to your system blade on the 360 into the network settings and go to the Sharing area of the
System Preferences on the MBP.

On the MBP make sure that your Airport Extreme connection is being shared with the Built-In Ethernet
(check the box next to Built In Ethernet and hit the start button at the top.).

Go into Network under System Preferences on the MBP.
Pick Built In Ethernet in the Drop Down menu. Write down the Subnet Mask and IP Address for the adapter,
you'll need that later.
Contact your router by punching it's IP into an internet browser. (I.E: 192.168.1.1).
This is usually the default IP for any router, so if you don't know what it is, try that one.
It'll also ask you for the password and username which are usually:

Login: admin
Pass: password

Login:
Pass: admin

or

Login: admin
Pass:

Once you're in find the DNS Addresses (DNS 1 and 2)
(under LAN not WAN if they're different) and write those down. Now it's time to go back to the Xbox.
In the settings tab you'll find a lot of stuff has been set to automatic.
This will not help you, so start changing the things to manual.
Once you get in there, input each piece of information like so:

IP Address: Have a look at the address of the Ethernet Adapter.
Copy it digit for digit only make the last number lower than the last number of the Ethernet Adapter.
(I.E if the Adapter is 111.211.13.5, make the 360 111.211.13.4)
Subnet: This is the Subnet Mask you got from the Ethernet Adapter.
Gateway: This is the IP address of the Ethernet Adapter (NOT the address of your router)
DNS: These are the DNS numbers you got from your router.

Now, before you allow the Xbox 360 to test the connection, make sure that you have a
wireless internet connection coming in on the mac, and that you're sharing it with the ethernet card.
Also, though I haven't tested it yet, keep the Ethernet card on DHCP. Putting it on manual might mess things up.

Et Voila! Let the 360 run the tests.
There's one test that'll take extra long to do but don't fret, it eventually goes through and works splendidly.
