Internet Sharing not working?

Hi guys,

I have a problem with my MacBook Pro, recently updated to 10.5.7

For some reason, I can't get Internet Sharing to work. It used to work when I was back in 10.5.6, but one day it just stopped working. I want to share from Ethernet and out via Airport (so I can use my iPhones as I don't have 3G access on campus residence). Even if I have airport on, I can't get the "internet shared" icon (that would be in place of the airport icon up in the task bar when Internet Sharing is activated) to show even if I check Internet Sharing in System Preferences. I've tried restarting, I've updated everything that can be updated but I still can't get it to work.

Anybody have any clues?

I've had the same problem described in this thread (and several others) for 2 or 3 months now, both with Mac OS 10.5.7 and 10.5.8. I tried everything described here multiple times with no improvement -- my MacBook Pro can attach to the AirPort net created by my iMac, but it does not get internet service.

I called Apple Care today, and on the third representative we found the problem: In System Preferences/Security/Firewall "Allow all incoming connections" must be checked. Now it works fine.

I tried both of the above two suggestions, plus have tried basically every suggestion I can find. Nothing will work. I made a topic here as well but no one seems to know what to do.

Could anyone add knowyourmac@hotmail.com in Messenger and try to walk me through the problem? I would greatly appreciate it.

Maybe this solution for my problem will help you? See: http://echeng.com/journal/2009/07/06/encrypted-internet-sharing-between-mac-os-a nd-windows-xp/

Specifically, step 4 and 6 are crucial!:

1. In Mac OS X, enable Internet Sharing to computers using Airport
2. In AirPort Options, select 128-bit WEP encryption and enter a 13-character password
3. In Windows, add a new wireless network
4. Enter the SSID and select WEP encryption with Shared Network Authentication (not Open)
5. Uncheck “The key is provided automatically” and enter the 13-character password
6. In the Authentication tab, be sure that “Enable IEEE 802.1x authentication” is unchecked

Hope that helps you!
