- if you set it to "Block all incoming connections" it still allows access

query the Netbios naming service even with full blocking enabled.

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.
