See "Configuring a host network connection" on page 75. See "Configuring a remote network connection" on page 96. About Internet broadband connections Connecting over the Internet to a home-based network that uses a broadband solution such as a cable modem or DSL can present some challenges. Many home-based broadband Internet solutions include a cable or DSL router, which lets multiple computers share a single Internet connection. The router uses Network Address Translation (NAT) technology to make this address sharing possible. In a sharing situation, this IP address is assigned to the router. The router, in turn, generates new IP addresses, and then assigns them to the individual computers that share the connection. When you subscribe to a broadband service, your Internet service provider (ISP) assigns you a single IP address. These router-assigned IP addresses are private and cannot be seen from the Internet. The only address that can be seen from the Internet is the IP address that is assigned to the router. Figure 1-1 shows how Internet broadband connections are made.
