After examining a given access-list, I can usually determine what it's goal is. When I have to write the access-list myself from scratch, I always seem to screw up.
Someone referred me to
http://www.subnettingquestions.com/ for tons of subnetting questions which was a great help when I wanted to drill subnetting into my head. Anything similar out ther for access-lists? Something that will keep drilling me until I perfect it.
thanks
