In addition to the files for the above lab, I have included detailed configuration instructions. If we translate this into normal language, we will get the following: “Redirect all packets, which I don't know, into the “outside" interface through the gateway 1.1.1.1" Cisco ASA “knows" only those networks that are directly connected to its interfaces or that are entered as routes in its running configuration.
