Just switched from PC to Mac this past week and Firewalls are very important for PC users and I've heard that Leopard's new firewall program is a joke. Being a computer illiterate I'm wondering what the ideal setting should be on Leopard. "Allow all connections" "block all connections" or "set each one". I just put on "block all" with "stealth mode." Hope I'm doing the right thing. Can anyone comment?
