Been spending the last few days doing some leg-work on understanding different ACL’s to match different networks most effeciently.
Alot of posting on Online-Study List on how to do this, all very valuable. Tyson Scott from IPexpert created a PDF file that was posted, and will also be made available from IPexpert.com in the member section. It gives some good examples of the binary math behind it all.
Also, I can highly recommended a free vLecture from IPexpert on this topic, it goes through some details on how it all fits together..
It can be found right here: Link
I will give further details on a later post about the understanding of it all. But take the time and go through the PDF and the free vLecture, it might contain the golden nugget you are looking for to understand it all.
