Cisco Packet Tracer
I went through an exercise in this tracer. My head is still reeling from all the terms. Basically I was setting up a virtual security appliance called the Cisco ASA 5505. Sure I could buy a physical box for $250 used. But this simulation made learning a lot easier. Plus the module gave me hints all throughout.
So far I configured some network interfaces, address translation, a DHCP server, authentication, a DMZ, static NAT to my server, and some ACLs. And that was just in the first hour. My head is definitely still spinning. This tool can definitely help you learn the Cisco operating system command line, as well as network security topics in general.
