I believe that the macintosh's firewall is advanced enough to be able to support this ability, but the simplified interface to it provided by "System Preferences: is insufficient to do this.
Your choices are: 1. Look at a separate piece of hard ware (ie Airport Base Station ) or other wireless router. I think you might even be able to manage with the Airport Express. 2. Install software that controls the firewall ie I believe there are at least three packages out there. I have never reviewed them. 3. Learn the configuration file for the internal Apple Firewall and configure as you feel appropriate. Tidbits.com's Rich Mogul had a long piece about the Leopard firewall changes shortly after Leopard came out. I have not specifically seen any discussions about Snow Leopard changes to the core firewall. Jon -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
