- if you set it to "Block all incoming connections" it still allows access to certain system services. We could access the ntp daemon that is running per default over the internet. In a LAN based scenario, we were able to

The firewall in Tiger, and presumably Leopard, only affects TCP services by default (you can enable UDP filtering in the Advanced settings). So no change here from the status quo.
