    Nop.. from my understanding it is theoretical but obviously unusable due to transport mechanism limitations. Bear in mind, I am still working on my first ccna so I could be embarrasingly wrong.

    Bah, why didn't you get the 5th???

    I think you might be missing NAT in the 4th edition. Go into the FAQ and read up on some of the book comparison topics. It'll tell you what you need to download in order to fill in what the 4th edition leaves out.
