I think Dr. Hyatt was talking about a NATed firewall, which is different than
something like Zone Alarm. For instance, at my house we have cable internet
connected to a router (little thing, looks like a hub), and we have four or five
computers with network cables plugged into that. One thing the router does
(among many others) is that to anyone on the internet, all of our family's
computers have the same IP address. The router sorts out the details and makes
sure the right data gets to the right computer at our house. This is
advantageous to us since we only have to pay for one IP address instead of four
or five. Now imagine a company that "hides" hundreds or thousands of computers
behind one IP address. There's no way of knowing which one of the thousand
computers a message came from.

127.0.0.1 is a reserved IP address, called the loopback address. Essentially it
is a way to refer to your own machine. It is useful for troubleshooting network
problems. If you can ping 127.0.0.1 successfully, then you know you're network
card is working at least, even if you can't connect to anything on the network.
