19. Introduction Reference Guide for the Model RT328 and Model RH348 ISDN Routers Using RIP routers update one another periodically and check to see if there are any changes to be added to the routing table An important consideration is the convergence time or how long it takes for a change to the routing topology such as a new node or a node failure to be propagated throughout the entire RIP environment To prevent this convergence process from being excessively long RIP is limited to 15 hops maximum The Model RT328 RH348 router supports both the older RIP 1 and the newer RIP 2 protocols Among other improvements RIP 2 supports subnetting and multicasting IP Addresses and the Internet Because TCP IP networks are interconnected widely across the world every machine on the Internet must have a unique address to make sure that transmitted data reaches the correct destination Blocks of addresses are assigned to organizations by the Internet Assigned Numbers Authority IANA Individual users and small organizations may obtain their addresses either from the IANA or from an Internet service provider ISP The Internet Protocol IP uses a 32 bit address structure The address is usually written in dot notation also called dotted decimal notation in which each group of eight bits is written in decimal form separated by decimal points For example the binary address 11000011 00100010 00001100 00000111 is normally written as 195

52. Operation Using NAT If multiple stations on a LAN need to access the Internet simultaneously they usually have to obtain a range of IP addresses from the ISP This type of Internet account is much more costly than a single address account typically used by a single user with a terminal adapter rather than a router The Model RT328 RH348 router employs a method called extended NAT This method allows an entire department of networked PCs to share an Internet account using only a single IP address which may be statically or dynamically assigned by your Internet service provider ISP The router accomplishes this address sharing by translating the internal LAN IP addresses to a single address that is globally unique on the Internet The internal LAN IP addresses can be either private addresses or registered addresses For more information about IP address translation refer to RFC 1631 The IP Network Address Translator NAT Figure 1 3 illustrates a single IP address operation Private IP addresses assigned by user IP addresses assigned by ISP 192 168 0 2 FOUDRE L TI86EA Figure 1 3 Single IP Address Operation Using NAT Introduction 1 13 Reference Guide for the Model RT328 and Model RH348 ISDN Routers This scheme offers the additional benefit of firewall protection because the internal LAN addresses are not available to the Internet through the translated connection All incoming

55. a filter set is reducing unnecessary calls by Windows 95 When using Windows 95 with a dial up ISDN router you may need to make some configuration changes to avoid having ISDN calls placed unnecessarily Most of these unnecessary calls are caused by PCs on the LAN trying to perform local NetBIOS name resolution either in response to a user action browsing the Network Neighborhood or turning a PC on or off for example or as periodic background activity In some cases this NetBIOS activity can be kept local by other means such as configuring a WINS or DNS server on the local network using an LMHOSTS file to store addresses of local hosts or turning off NetBIOS name resolution by DNS A simpler method is to filter NetBIOS traffic using the filtering capabilities of your Model RT328 RH348 router Diagnosing the Situation If you already know the source or types of packets that are causing the problem you can proceed directly to the design of the filter Otherwise you can use a sniffer or the router s built in tools to determine the source A particularly useful tool is the display in Menu 24 1 of the LAN Packet Which Triggered Last Call Figure 8 2 illustrates the header of the packet that caused an unwanted call to be placed LAN Packet Which Triggered Last Call Type IP 45 00 00 3E 9E 05 00 00 1F 11 CC 9D 8D FB 17 12 CF 45 BC B9 00 89 00 35 00 2A 63 C8 01 85 01 00 00 01 00 00 00 00 00 00 OA 53 41 4E 54 41 43 4C Figu
