Rules of the RoadWe have always found it very confusing when different addresses are used in the examples throughout a technical publication. For this reason we use the address space depicted in Figure I-2 when assigning network segments in this book. Please note that the address space we have selected is all reserved space per RFC 1918. We understand that these addresses are not routable across the Internet and are not normally used on outside interfaces. Even with the millions of IP addresses available on the Internet, there is a slight chance that we could have chosen to use an address that the owner did not want published in this book. Figure I-2. Addressing for ExamplesIt is our hope that this book will assist you in understanding the examples and the syntax of the many commands required to configure and administer the PIX Firewall. Good luck! |
