Smoothwall

Linuxformat magazine is offering on its CD this month a firewall package called 'Smoothwall.' Looking at the blurb, and reading the documentation, the software seems to good to be true from my persepctive (NQT learning to be sysadmin in between marking, previous experience as a casual desktop user). Does anyone have any experience of using smoothwall and can share pros and cons? Many thanks Darren Garside
