Chapter 1 Introduction This chapter describes the features of the NETGEAR Model RT338 ISDN Router and discusses planning considerations for installation. About the Router The Model RT338 router transports data from one local area network (LAN) to another through a wide area network (WAN) connection. The router compares the network addresses of data packets sent through the LAN to the entries in its address tables.
PAGE 24
Reference Guide for the Model RT338 ISDN Router Key Features The Model RT338 router provides the following features: • • • Standard basic rate ISDN (BRI) connection – ISDN, 2B+D, providing two 64 Kbps data channels and a 16 Kbps control channel – Two-wire U interface with internal NT-1 adapter Protocol Support – IP routing – Multilink Point-to-Point Protocol (PPP) for 128 Kbps operation – Dynamic bandwidth-on-demand with Bandwidth Allocation Control Protocol (BACP) – Dynamic extended Network
PAGE 25
Reference Guide for the Model RT338 ISDN Router • • 10M or 100M Ethernet connectivity – RJ-45 interface allowing connection to a 10BASE-T or 100BASE-T network – Autosensing Analog voice ports – Provides two RJ-11 interfaces – Provides CallerID signaling to external attached devices – Allows a standard analog Public Switched Telephone Network (PSTN) device (for example, telephone, fax, or modem) to make and receive calls from other ISDN or PSTN connected devices – Eliminates the need for a sepa
PAGE 26
Reference Guide for the Model RT338 ISDN Router Multilink PPP Support When the single-channel ISDN line utilization exceeds a configurable threshold, the router can automatically establish an additional ISDN call to provide additional bandwidth. During heavy traffic, the two 64 Kbps B channels are combined using Multilink PPP to provide a fast 128 Kbps pipe. When traffic slows down, one of the B channels is idled to save toll charges.
PAGE 27
Reference Guide for the Model RT338 ISDN Router DNS Proxy When DHCP is enabled and no DNS addresses are specified, the router provides its own address as a DNS server to the attached PCs. The router obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN. Security The Model RT338 router is equipped with several features designed to maintain security, as described in this section.
PAGE 28
Reference Guide for the Model RT338 ISDN Router Management Support The router is designed to be installed and made operational within minutes after connection to the network. If you use a PC computer, you can use the FirstGear software to easily configure the unit from the Windows environment. For more information about the FirstGear software, see Chapter 5, “Using FirstGear to Configure Internet Access.
PAGE 29
Reference Guide for the Model RT338 ISDN Router Routing Information Protocol One of the protocols used by a router to build and maintain a picture of the network is the Routing Information Protocol (RIP). Using RIP, routers update one another periodically and check if there are changes to be added to the routing table. The Model RT338 router supports both the older RIP-1 and the newer RIP-2 protocols. Among other improvements, RIP-2 supports subnet and multicast protocols.
PAGE 30
Reference Guide for the Model RT338 ISDN Router There are ﬁve standard classes of IP addresses. The address classes determine the network and host sections of the address differently. Address classes allow 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. After the address class has been determined, the software can correctly identify the host section of the address.
PAGE 31
Reference Guide for the Model RT338 ISDN Router This addressing structure lets IP uniquely identify each physical network and each node on each physical network. For each unique value of the network portion of the address, the base address of the range (host address of all zeros) is known as the network address and is not usually assigned to a host.
PAGE 32
Reference Guide for the Model RT338 ISDN Router 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. If each end of a routed link requires a different network number, such a structure is an inefficient use of addresses. It is unlikely that smaller office LANs require that many devices. You can resolve this problem by using a technique known as subnet addressing.
PAGE 33
Reference Guide for the Model RT338 ISDN Router Although the preceding example uses the entire third octet for a subnet address, note that you are not restricted to octet boundaries in subnetting. To create more network numbers, you need only shift some bits from the host address to the network address. For instance, to partition a Class C network number (192.68.135.0) into two, you shift 1 bit from the host address to the network address. The new netmask (or subnet mask) is 255.255.255.128.

PAGE 35
Reference Guide for the Model RT338 ISDN Router Single IP Address Operation Using NAT In the past, if you needed multiple PCs on a LAN to access the Internet simultaneously, you would have to obtain a range of IP addresses from the Internet service provider (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 Model RT338 router employs an address-sharing method called Network Address Translation (NAT).
PAGE 36
Reference Guide for the Model RT338 ISDN Router This scheme offers the additional benefit of protection similar to that of a firewall. Internal LAN addresses are not available to the Internet through the translated connection. All incoming inquiries are filtered out by the router. Filtering can prevent intruders from probing your system. You can use the port forwarding feature to allow specific services (for example, a Web server) on your local network to be accessible to outside users.
PAGE 37
Reference Guide for the Model RT338 ISDN Router 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 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 obtain this configuration information automatically.

Filter.fm Page 1 Friday, October 6, 2000 5:28 PM Chapter 9 Configuring Filters This chapter describes how to use and configure filters for your Model RT338 ISDN Router. The router uses filters to decide whether to allow passage of a data packet and/or to make a call over the ISDN line. Three types of filters are involved: incoming data filters, outgoing data filters, and call filters. Data filters screen the data to determine if the packet should be allowed to pass.
PAGE 149
Filter.fm Page 2 Friday, October 6, 2000 5:28 PM Reference Guide for the Model RT338 ISDN Router Router Filter Structure You can configure up to 12 filter sets, each with up to six rules. For IP packets, these rules involve comparing the protocol type of a data packet (for example, TCP, UDP), source or destination address, or port number. Also, a generic filter may be defined to merely test for a byte or pattern of bytes in a particular location in the packet.

Filter.fm Page 3 Friday, October 6, 2000 5:28 PM Reference Guide for the Model RT338 ISDN Router Select the filter that you want to configure or choose an unused set to create a new filter. 2. In order to distinguish between the 12 filter sets, each filter set should have a name or description. When you select a set for editing, you are prompted to provide descriptive text to be displayed in the comment field of Menu 21 next to the filter number.
