I'm trying to enable "DVD or CD Sharing" in the System Preferences. When I enable it, it says that the Firewall is blocking it. If I go into the Security > Firewall settings, I see that the first item under Advanced... is "DVD or CD Sharing" and that it's set to "Allow incoming connections".

If I disable the Firewall completely, it works correctly. Is there any way to get it to work with the Firewall enabled, though?

Have you tried connecting to your Mac and using the shared media? It seems that the "Blocked by firewall" -message, even though you have it alled in Firewall, is a bug. –  deiga Feb 21 '11 at 2:56

We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.

Can you describe the detailed instructions a bit better? –  CajunLuke Sep 5 '12 at 17:11
