Internet Sharing Issues solved.

After installing 10.2 and setting up internet sharing with either Brickhouse or the built-in tools my client systems were unable to connect to certain web sites, use sherlock or iTunes radio stations.

At apple I found a document detailing how the MTU size on clients of Internet Sharing were too large for certain ISP routers. The document detailed a problem supposedly only applying to Japan however I am with BellSouth in the United States.

Using this simple terminal command on my clients enabled them to use all services: Sherlock, the entire Web (some sites worked and some didn't without the adjusted MTU) and iTunes radio stations.

1. Open Terminal (/Applications/Utilities/).
2. At the prompt, type: sudo ifconfig en0 mtu 1454
3. Press Return.
4. Type your Admin user password when prompted, then press Return.
5. Quit Terminal.

I searched for two days to find the solution to this problem and so I thought I'd share it with others. I think you can do the same under OS 9 with sustworks IPNetTuner software.

Note the command needs to be issued every time the box starts up. I'm going to write a shell script to do this and may post it here later but I figure this is enough for now.

I hope this helps any other BellSouth users and anybody else having trouble sharing their internet connections!
