How do I share my wireless internet connection over Ethernet?

Question

I want to achieve the same thing with Windows XP that I do with Mac OS X. On my Mac I use "Internet Sharing" from "Wi-Fi" to "Ethernet".

What I'm trying to do is connect my freesat top-set box to my wireless connection. The Freesat box only has a wired ethernet connection.

What I want to do is connect my laptop ethernet connection to the freesat-box ethernet connection and share my laptop's wifi to the laptops ethernet connection

Edit: Also I need the laptop or the wifi DCHP server to address the freesat-box.

Solution

It is called Internet Connection Sharing in Windows XP. There is a nice tutorial here.

Excerpt:

On the host computer:

• Log on to the host computer as Administrator or as Owner.
• Click Start, and then click Control Panel.
• Click Network and Internet Connections.
• Click Network Connections.
• Right-click the connection that you use to connect to the Internet. For example, if you - connect to the Internet by using a modem, right-click the connection that you want under Dial-up.
• Click Properties.
• Click the Advanced tab.
• Under Internet Connection Sharing, select the Allow other network users to connect through this computer's Internet connection check box.

On the client computer:

• Log on to the client computer as Administrator or as Owner.
• Click Start, and then click Control Panel.
• Click Network and Internet Connections.
• Click Network Connections.
• Right-click Local Area Connection, and then click Properties.
• Click the General tab, click Internet Protocol (TCP/IP) in the This connection uses the following items list, and then click Properties.
• In the Internet Protocol (TCP/IP) Properties dialog box, click Obtain an IP address automatically (if it is not already selected), and then click OK.

Is wiring impossible? It looks non feasible to have your laptop on for your Freesat box.

No. Unfortunately not. My concept works on my Mac but I'm struggling with Win XP.

@Simon: Sorry Simon I don't understand. Is it "Internet-->Freesat==>something-->laptop" or is it "Internet-->Freesat==>laptop==>something-->others"? Or is it "Internet==>wifirouter-->laptop==>something==>Freesat"? ("--" is wired, "==" is wireless).
