In other words, learn to use it. I know it's difficult, but it will be worth it. The "go'n buy & setup" sound like M$-plug-and-play. It would create a generic firewall. It may or may-not full protect your system. I would recommend reading http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/firewalls.html as well as reading the freebsd questions mail archives. 2...The following quote: "which will shutdown until all system-files are moved into RAM" maybe you ment to say move out of ram before shutdown. If you have a "UPS", then good, otherwise consider getting one. You could end up with a corrupt file system. 3...Do you have a cd-rom drive? You could run Freesbie: www.freesbie.org -- Alexander FreeBSD 6.0-RELEASE i386
