Hola there! from a MacBook Pro on OS X 10.6.4 Straight to the point: On System Preferences > Sharing, I have the "DVD or CD Sharing" checkbox ticked, i.e. Service = On, however on the right hand side of the pane the on/off dot is red and it reads "DVD or CD Sharing: Blocked by Firewall". Problem is that on System Preferences > Security > Firewall > Advanced , "DVD or CD Sharing" appears set to "Allow incoming connections". So what am I missing here?? In case it helps, the options on Firewall's Advanced pane I've tried are: - "Block all incoming connections" - UNchecked - "Automatically allow signed software to receive incoming connections" - checked - "Enable stealth mode" - both checked and unchecked. Muchas gracias in advance for your much needed help! Alberto
Well since you are using a firewall bookmark the Apple document Well known TCP and UDP ports used by Apple software products.
