How do I auto start a firewall for myself and other users of this computer

Nohow -- firewall starts automatically by default.

Note: Firestarter is not firewall -- it's only configuration thing -- you set some rules and they are applied. Firewall is called iptables and it's part of kernel.

 Thank you for quick and succinct response. So iptables is always on and will protect the computer. Is it auto updated if required? Thanks again, ShawJ
