NAT and Security Sections

Well I finished my NAT and security sections, just finished up the NAT chapter in Routing TCP/IP Vol II.  Great read btw.  I NEED to do some labbing, but dont want to go all hardcore labbing right away when I should be plugging away at reading and theoretical knowledge.  I will probably round the day out with some practice Boson tests, and go from there.  I am a bit under the weather, so long, prolonged studying is hard.
