PC to use Mac's internet connection

I thought the internet sharing worked only over airport.

You may need a router to allow them to share the connection. Are they networked via ethernet cable or wireless?

yeah, a router might be the best platform-free solution. you want an ethernet modem for your cable or dsl connection, then that can connect to a router, which will have multiple ethernet ports and will work well with Macs and PCs.

Internet sharing works over any interface, not just Airport.

In you Network prefs, when you show Network Port Configuration, your internet connected ethernet port should be at the top of the list, and the 2nd ethernet port should be number 2 in the list.

When internet sharing is turned on, the internet connection on the top port should be shared with the internet connection on the second line.

I have two comments. First, go with a router; you get a lot more flexibility, and a good bit of protection using one of the popular gateway routers. You can find a good one on sale for less than $50US.

Second, is there a good reason your PC is running WinME? That OS has the distinction of featuring the very worst of both branches of the Microsoft OS line-it doesn't have the flexibility or compatibility of the Win98 branch, and it wants to (but fails to) provide the security that the NT/2K/XP branch actually does provide. Hunt down XP (Pro, not Home) and use that. If you're in college, you can probably get a very good deal on it. XP is far more compatible with everything (and shows signs of a solid Unix underpinning set, not as complete as OS X, but a good start), and it will be supported for many years, while ME is no longer supported by MS-they gave up on it.

Good luck.

When you say the PC 'cannot connect to the internet' what do you mean? Can the PC ping anything out there on the internet (by IP)?

If so then one thing to check is that with the PC you may have to put in DNS info manually, it will not pick it up automatically from the mac, which picked it up automatically from the ISP.

Great point. On the PC right click on "Network Neighborhood" and look at the settings tabs, or better yet, open a command prompt box (a "DOS Box") and type "ipconfig" (without the quotes). You'll find out what your machine's IP is (it should be on the correct subnet for your Mac's second ethernet card), and whatever DNS settings it has picked up. If those DNS entries are "0.0.0.0" then the PC hasn't gotten the data from the Mac, and you'll have to enter them manually via the network properties applet.

Good idea. I don't think ipconfig is a valid command in ME, only in NT kernel oses. But you can run winipcfg and check that data. The main thing is to make sure you have DHCP configured. There really shouldn't be much configuration on the windows pc. It should automatically acquire the information from the mac. Like other posters have mentioned, your best bet is to get a hardware router. They're becoming fairly affordable and offer more flexiblity.

I have been looking for this info too, and it's so simple, but not in macos help what u need to do is (in 10.2 and later) go to file sharing in system prefs and set internetsharing on , on ur second ethernetcard. In the pc set in controlpanel network tcpip prefs the tab to dhcp and don't forget to fill in the settings in the tab dns config as follow host=FOO and then u fill in the dns servername of ur isp in domain like apple.com or whatever . Restart the pc and u should be on the net.
I hope but it worked for me. There is nothing in the help regarding the settings on the 2nd computer and that is really bad.
