Appendix B Networks, Routing, and Firewall Basics This chapter provides an overview of IP networks, routing, and firewalls. Basic Router Concepts Large amounts of bandwidth can be provided easily and relatively inexpensively in a local area network (LAN). However, providing high bandwidth between a local network and the Internet can be very expensive. Because of this expense, Internet access is usually provided by a slower-speed wide-area network (WAN) link such as a cable or DSL modem.
Reference Manual for the Model FR114P, FR114W and FM114P Cable/DSL ProSafe Firewall Family Routers vary in performance and scale, number of routing protocols supported, and types of physical WAN connection they support. The FR114P, FR114W and FM114P Cable/DSL ProSafe Firewalls is a small office router that routes the IP protocol over a single-user broadband connection.
Reference Manual for the Model FR114P, FR114W and FM114P Cable/DSL ProSafe Firewall There are five standard classes of IP addresses. These address classes have different ways of determining the network and host sections of the address, allowing for different numbers of hosts on a network. Each address type begins with a unique bit pattern, which is used by the TCP/IP software to identify the address class.
Reference Manual for the Model FR114P, FR114W and FM114P Cable/DSL ProSafe Firewall Family • Class D Class D addresses are used for multicasts (messages sent to many hosts). Class D addresses are in this range: 224.0.0.0 to 239.255.255.255. • Class E Class E addresses are for experimental use. This addressing structure allows IP addresses to uniquely identify each physical network and each node on each physical network.
Reference Manual for the Model FR114P, FR114W and FM114P Cable/DSL ProSafe Firewall Subnet Addressing By looking at the addressing structures, you can see that even with a Class C address, there are a large number of hosts per network. Such a structure is an inefficient use of addresses if each end of a routed link requires a different network number. It is unlikely that the smaller office LANs would have that many devices. You can resolve this problem by using a technique known as subnet addressing.
Reference Manual for the Model FR114P, FR114W and FM114P Cable/DSL ProSafe Firewall Family Note: The number 192.68.135.127 is not assigned because it is the broadcast address of the first subnet. The number 192.68.135.128 is not assigned because it is the network address of the second subnet. The following table lists the additional subnet mask bits in dotted-decimal notation.

Netmask Formats 255.255.255.252 /30 255.255.255.254 /31 255.255.255.255 /32 NETGEAR strongly recommends that you configure all hosts on a LAN segment to use the same netmask for the following reasons: • So that hosts recognize local IP broadcast packets When a device broadcasts to its segment neighbors, it uses a destination address of the local network address with all ones for the host address.
Reference Manual for the Model FR114P, FR114W and FM114P Cable/DSL ProSafe Firewall Family Single IP Address Operation Using NAT In the past, if multiple PCs on a LAN needed to access the Internet simultaneously, you had to obtain a range of IP addresses from the ISP. This type of Internet account is more costly than a single-address account typically used by a single user with a modem, rather than a router. The FR114P Firewall employs an address-sharing method called Network Address Translation (NAT).
Reference Manual for the Model FR114P, FR114W and FM114P Cable/DSL ProSafe Firewall This scheme offers the additional benefit of firewall-like protection because the internal LAN addresses are not available to the Internet through the translated connection. All incoming inquiries are filtered out by the router. This filtering can prevent intruders from probing your system.
Reference Manual for the Model FR114P, FR114W and FM114P Cable/DSL ProSafe Firewall Family IP Configuration by DHCP When an IP-based local area network is installed, each PC must be configured with an IP address. If the PCs need to access the Internet, they should also be configured with a gateway address and one or more DNS server addresses. As an alternative to manual configuration, there is a method by which each PC on the network can automatically obtain this configuration information.
Reference Manual for the Model FR114P, FR114W and FM114P Cable/DSL ProSafe Firewall Stateful Packet Inspection Unlike simple Internet sharing routers, a firewall uses a process called stateful packet inspection to ensure secure firewall filtering to protect your network from attacks and intrusions. Since user-level applications such as FTP and Web browsers can create complex patterns of network traffic, it is necessary for the firewall to analyze groups of network connection "states".
