Add servers to a DMZ where they can be more publicly accessible than your desktop systems.
Chapters 24 though 27 explain how to configure different server types, and Chapter 18
describes how to set up Linux as a router/firewall. Chapter 18 includes details on how
to configure features such as IP Masquerading, NAT, and packet forwarding.
Connecting Other Equipment
Although I??™ve focused on basic Ethernet equipment and dial-up modems for configuring network
connections, Linux supports many, many other types of network equipment as well as different
protocols for communicating over that equipment. Here are a few examples:
ISDN??”Integrated Services Digital Network (ISDN) lines were the preferred method of
high-speed data lines to small businesses in the United States before DSL became widespread.
It is still popular in Europe, but is being supplanted by more affordable DSL
equipment. ISDN4Linux drivers and tools are available in many Linux systems for connecting
to ISDN networks.
USB cable modem??”Most cable modems offer an Ethernet port that you can connect to
directly from your computer??™s own Ethernet port. However, if you don??™t have an Ethernet
port, often you can connect to the cable modem through one of your USB ports.
