Rules ?

[Michael Givens]

I am new to the Gnat family and am trying out the gb-light version, and was wondering are they any web sites that perhaps have a little better documentation then the actual user manual ?   Right now I run a Firewall 1 box at work, (don't hate me) and I am checking out the Gnat box for our new T-1 we will be getting, and some times user docs are just a little hard to understand.  Now I am not stupid, just confused on some of the rules and why they are that way !   Please point me in the right direction.   TIA,   Mike
