Testing AnyConnect With Packet Tracer

KB ID 0001298 Dtd 05/04/17 Problem Packet tracer is a great tool, I wrote about it in the ‘Prove It’s Not the Firewall‘ article a while ago.

KB ID 0001256 Dtd 09/11/16 Problem This was asked as a question on Experts Exchange this week, and it got my interest. A quick search turned up a bunch of posts that said, yes¬†this is possible, and you deploy it with FreeRADIUS and it works great. The problem was, a lot of the information is a little out of date, and some of it is ‘wrong enough’ to make the non-technical types give up. But I persevered, and got it to work....
