I thought I would write a step by step guide on how to connect to Xbox live through a pc/laptop since many people are having trouble with it. There are many advantages to using this method but my favourite is that I can connect to Xbox Live wirelessly using my laptop. No need to fork out €80 euro on a wireless adapter.
This method will be explained using windows vista and eircom broadband with a netopia router. If your are using XP this guide will still work however the layout for your internet connections will be different.
You will need: An Ethernet cable (like the one included with your Xbox), a pc/laptop connected to the internet via wifi, and of course an Xbox.
Your first step will be to set your firewall to low. This is simple and was already explained here by Timans.

Next is to enable ICS.
1. Click Start, click Control Panel, click Network and Internet, click Network and Sharing Centre and then, on the left, click Manage network connections.
2. Right-click on your wireless connection, and then click Properties.
3. Click the Sharing tab and enable the 'allow other network users to connect through this computer's internet connection' option. Click ok.
Now connect the Ethernet cable to your pc and to your Xbox. Give it a minute to connect and then on your Xbox go to the system tab and click network settings. Next click 'test Xbox live connection'. If everything worked as it should the test should finish ok except the NAT settings will be set to strict.
This is the point where most people get stuck. Strict means that your router is not letting certain information through. You can still connect to Xbox live and play some games but other features will not work (voice chat, ranked games ECT...)
The only way to set NAT to open is to open certain ports on your router so the information will be allowed through (this is called port forwarding), however port forwarding will not work when you are connected through this method. The only way it will work is to bridge your wireless connection and you Local Area Connection.
1. Click Start, click Control Panel, click Network and Internet, click Network and Sharing Centre and then, on the left, click Manage network connections.
2. Right-click on your wireless connection, and then click Properties.
3. Click the Sharing tab and DISABLE the 'allow other network users to connect through this computer's internet connection' option. Click ok.
A NETWORK BRIDGE WILL NOT WORK WITH ICS ENABLED.
4. Disconnect for your internet connection (or switch of wifi if your laptop has a switch for it). YOU WILL NOT BE ABLE TO BRIDE A CONNECTION IF YOU ARE CONNECTED TO THE INTERNET.
5. Highlight the Local Area Connection and the Wireless Network Connection, right click and either of them and select ‘bridge connection’. When complete you can reconnect to the internet.
6. Open any webpage just to make sure you can still connect to the internet.
Test your Xbox live connection again, just to make sure it is connecting. You NAT settings will still be set to strict, so now you must open the correct ports.
1. On your pc go to your router homepage (open internet explorer/firefox and go to 192.168.1.254).
2. Click custom services on the left and in the ‘service name’ dropdown box select ‘Xbox live games’. It will be near the bottom of the list. Click enable and in the ‘select host device’ dropdown box select the pc your Xbox is connected to. Click enable.
And you’re done. Test your Xbox live connection again just to be sure but your NAT settings should be set to open.
Let me know if your having any problems and ill try help.
Enjoy Xbox live!!!
