Chapter 4 - RASFinder Software
Chapter 4 - RASFinder Software Introduction This chapter describes the RASFinder software and explains how to make changes to the configuration of your RASFinder. The major configuration parameters were established during the loading of the software (Chapter 3) and initial configuration. The RASFinder software and configuration utilities enable you to make changes to that initial configuration. The RASFinder software enables you to refine your configuration based on your network connections.
Chapter 4 - RASFinder Software RASFinder Setup All changes to your RASFinder configuration are initiated through the RASFinder - Router Setup menu. You can view or change your RASFinder configuration in Windows 98, 2000, XP and Windows NT by clicking Start | Programs | RASFinder | Router Configuration, or double-clicking the Router Configuration icon in the RASFinder program group, if it displays on your desktop. After loading, the RASFinder - Router Setup menu displays.
Chapter 4 - RASFinder Software Typical Applications The two basic applications for the MTASR3-200 RASFinder are (1) as a Remote Access Server (RAS) to permit remote users to dial into a local area network and use the resources of that network and (2) as a Router for LAN-to-LAN routing. The RASFinder defaults to a RAS configuration during the initial software loading. Typical examples of both types of applications are presented in the following paragraphs.
Chapter 4 - RASFinder Software network. The address assigned to the Ethernet port of the RASFinder can be any address that is recognizable by your network’s backbone. After you enter your LAN IP address information and three sequential WAN addresses have been automatically placed in the Remote address for WAN 1, 2, and 3 fields, ensure that the Enable IP Routing on WAN 1, 2, and 3 are checked. This activates the WAN ports to receive calls from the remote users.
Chapter 4 - RASFinder Software attributes or any other custom attributes on the Radius Security Server. The Enable RADIUS option enables communication between the Radius server and the RASFinder. Enable Accounting option activates the accounting features which allow the Radius server to track the number of bytes sent and received, login and logout times, port number, etc.
Chapter 4 - RASFinder Software RAS Application using Remote User Database The initial software loading process would be the same as for the RAS application using Radius, except that now instead of setting up Radius parameters, you will assemble a Remote User Database. A typical RAS application using the Remote User Database is shown in Figure 4-2. Figure 4-2.
Chapter 4 - RASFinder Software information (for one remote user at a time) via the Add Users dialog box. The user name and password in this application must be negotiated between the RASFinder administrator and each remote user. User names can be up to 39 characters long, with any printable characters; however, no spaces are allowed within the names. In our dialog box (above), we are using the User Name “User2.
Chapter 4 - RASFinder Software Inbound Permissions using Telnet, or Inbound using Rlogin. The time of day and days in which the user can access the network are the final items in the User Permissions dialog box. Once this is established for each user and the user database is loaded into the RASFinder, all the remote users can dial into the network and access the network resources according to the restrictions/permissions on this dialog box.
Chapter 4 - RASFinder Software Router Application The second basic application for the RASFinder is LAN-to-LAN routing as shown in Figure 4-3. The RASFinder is initially configured for a RAS application. To configure the RASFinder for a router application, you have to change the WAN port addresses to be on a different network from the LAN port. The remote WAN ports have to be on the same network as the local WAN ports.
Chapter 4 - RASFinder Software from a RAS application to a routing application. The PPP/SLIP (Point-to-Point/Serial Line Internet Protocol) button displays the PPP Port Setup dialog box with the WAN 1 tab active. In the Remote Port Setup group in the lower right of the dialog box, change from the Client only option to the Client or LAN (as shown below); this disables the Client only option, and enables the RASFinder to communicate with either a remote client (PC) or a LAN.
Chapter 4 - RASFinder Software You must now decide which protocol your LAN is using and choose that protocol from the main menu. For example, to configure the RASFinder for IP, the Port IP Address and IP Mask fields in the IP Port Setup dialog box display the information that was entered earlier for your Default Parameters during initial software loading. When you click the IP Port WAN tabs, the RAS LAN IP address appears in the Port address field for the WAN ports.
Chapter 4 - RASFinder Software IP Setup The IP Port Setup dialog box enables you to change the IP routing capabilities that were set up during software installation. This dialog box has five tabs: Ethernet, WAN 1, WAN 2, WAN 3, and Advanced. The Ethernet tab enables you to configure various parameters relating to the Ethernet port.
Chapter 4 - RASFinder Software Routing Information Protocol, Version 2 (RIPv2) RIPv2 has enhanced “explicit” netmask information and supports several new features including external route tags, subnet masks, next-hop addresses, and authentication. Subnet mask information makes RIP more useful in a variety of environments and enables the use of variable subnet masks on the network. Support for next-hop addresses permits the optimization of routes in an environment that uses multiple routing protocols.
Chapter 4 - RASFinder Software remote IP address must fall within the same IP network as the local WAN IP address. The Advanced tab is used to enable IP routing and RIP authentication and defines how the Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) servers are to be used. This tab is also used to set up the default route, any filters, OSPF (Open Shortest Path First), and Static Routes.
Chapter 4 - RASFinder Software normally used when a part of an internetwork can be reached by only one particular path. Static routes are manually configured routes that specify the transmission path a data packet must follow based on the data packet’s destination address. A static route could enable a client pc on the manufacturing network to send a document to the printer on the corporate network. This static route is shown in the top network in Figure 4-4.
Chapter 4 - RASFinder Software 192.168.2.220 which is pointing at the Internet router. You then, need to go into the IP Port Setup dialog box, select the WAN 2 tab, and activate the Unnumbered Link option. When you do this, the Port Address and the Remote Address groups become inactive. You should turn off RIP in the Support group on WAN 2 so that the RASFinder does not try to broadcast RIP packets which take up unnecessary bandwidth.
Chapter 4 - RASFinder Software Filters The network administrator can set up filters on the RASFinder for better control. Filtering can be used when you want to block all packets originating from a specific destination (called source address filtering) or all packets heading for a particular destination (called destination address filtering). Filters can be set up to exclude packets of a particular protocol (TCP or UDP) or any particular field in a LAN packet.
Chapter 4 - RASFinder Software Add/Edit IP Port Filter dialog box, the protocol that is going to be filterred is TCP, the physical port on which the filtering is going to take place is the LAN port, the protocol port is telnet which translates into protocol port number 0023 in the filtering list window, and the filter type is Filter on Destination Port which means to drop all IP packets whose destination protocol port is telnet.
Chapter 4 - RASFinder Software IPX Setup The IPX Virtual Port Setup dialog box is used to control the four frame types and set up the three WAN ports of the RASFinder. The Advanced tab opens an IPX general setup window used to enable or disable IPX routing and autolearn of Ethernet network numbers; also, the distributed name of the RASFinder can be designated here.
Chapter 4 - RASFinder Software Bandwidth Optimization Group Discard Serialization Packets, when enabled (checked), causes the IPX router to discard Novell Netware File Server serialization security frames received from the specified virtual IPX port. Novell Netware File Servers implement broadcast frames, often referred to as security frames, that contain serialization information regarding the license of the file server executable.
Chapter 4 - RASFinder Software IPX Filters The network administrator can set up filters on the RASFinder for better control. IPX packet filtering can be set up to selectively filter or forward packets based on the IPX address. Filtering can be used when you want to block all packets originating from a specific destination (called source address filtering) or all packets heading for a particular destination (called destination address filtering). Filters can be set up to exclude packets of a specific port.
Chapter 4 - RASFinder Software Spanning Tree Setup This dialog box lets you configure the parameters for transparent bridging or bridging using Spanning Tree Algorithm as specified in IEEE 802.1d standard. Transparent bridging occurs between two remote Ethernet LANs. Spanning Tree Algorithm is a protocol specified by the IEEE 802.1d standard for use by bridges to perform bridging.
Chapter 4 - RASFinder Software performance degradation. The add or edit Spanning Tree Filter dialog box allows you to enter the Ethernet address (for example 15345678) to which you want to apply filtering, the physical port (WAN 1) on which the filtering is going to be applied, and the filter type in our example of Filter Destingation Address. This means that all packets with a destination address of 15345678 going to WAN 1 are dropped.
Chapter 4 - RASFinder Software WAN Port Setup The WAN Port Setup dialog box controls how each WAN port is configured. Since each port has a built-in modem, the default Mode, “Asynchronous” cannot be changed. The Connection Method can be set to either Answering or Dialing. If Dialing is enabled, then the number to be dialed has to be entered in the Dial Number field. The entry Multi-Tech 56K Socket Modem in the Modem Types field refers to the built-in modem installed in the RASFinder.
Chapter 4 - RASFinder Software Point-to-Point Setup The PPP Port Setup dialog box controls the WAN port protocol, dial on demand, and remote port setup. The WAN port protocol can be either Point-to-Point Protocol (PPP) or Serial Line Internet Protocol (SLIP). Of these two protocols, PPP is the more robust as it enables the endpoints to negotiate the use of the link and protocol parameters in a standardized way and also enables for standardized encapsulation of the packets.
Chapter 4 - RASFinder Software Applications In addition to local configuration, the RASFinder supports various applications that enable remote viewing and changing of the configuration from anywhere on the connected internetwork. To manage these applications, click Others on the Router Setup menu. The Applications Setup dialog box appears. Verify that the desired applications are enabled (checked). The default condition is all applications are checked.
Chapter 4 - RASFinder Software Client The information provided in this section enables multiple users to configure their PCs to access the LAN through a RASFinder. The RASFinder was configured by the administrator who, while installing the software, determined that the RASFinder would either automatically assign Internet (IP) addresses, or require that they be assigned manually to each client PC.

On underflow, the modem sends HDLC flag idle (0x7E) to the remote modem. This special error correction mode is overridden by any of the following commands: &F, &M, &Q, and \N.
Appendixes Appendix E - TCP/IP TCP/IP TCP/IP (Transmission Control Protocol/Internet Protocol) is a protocol suite and related applications developed for the U.S. Department of Defense in the 1970s and 1980s specifically to permit different types of computers to communicate and exchange information with one another. TCP/IP is currently mandated as an official U.S. Department of Defense protocol and is also widely used in the UNIX community.
Appendixes (connectionless) service. Some applications, such as those that involve a simple query and response, are better suited to the datagram service of UDP because there is no time lost to virtual circuit establishment and termination. UDP’s primary function is to add a port number to the IP address to provide a socket for the application.
Appendixes Internet Protocol (IP) IP is the Internet standard protocol that tracks Internetwork node addresses, routes outgoing messages and recognizes incoming messages, allowing a message to cross multiple networks on the way to its final destination. The IPv6 Control Protocol (IPV6CP) is responsible for configuring, enabling, and disabling the IPv6 protocol modules on both ends of the point-to-point link. IPV6CP uses the same packet exchange mechanism as the Link Control Protocol (LCP).
Glossary of Terms
Glossary A Access: The T1 line element made up of two pairs of wire that the phone company brings to the customer premises. The Access portion ends with a connection at the local telco (LEC or RBOC). Accunet Spectrum of Digital Services (ASDS): The AT&T 56K bps leased (private) line service. Similar to services of MCI and Sprint. ASDS is available in nx56/64K bps, where n=1, 2, 4, 6, 8, 12.
Glossary Basic Rate Interface (BRI): An ISDN access interface type comprised of two B-channels each at 64K bps and one Dchannel at 64K bps (2B+D). Bell Operating Companies (BOC): The family of corporations created during the divestiture of AT&T. BOCs are independent companies which service a specific region of the US. Also called Regional Bell Operating Companies (RBOCs).
Glossary Channel: A data communications path between two computer devices. Can refer to a physical medium (e.g., UTP or coax), or to a specific carrier frequency. Channel Bank: A device that acts as a converter, taking the digital signal from the T1 line into a phone system and converting it to the analog signals used by the phone system. A channel bank acts as a multiplexer, placing many slowspeed voice or data transactions on a single high-speed link.
Glossary across the interface to the specified “address”. The DLCI is confirmed and relayed to its destination, or if the specification is in error, the frame is discarded. Data Terminal Ready (DTR): A control signal sent from the DTE to the DCE that indicates that the DTE is powered on and ready to communicate. Dataphone Digital Service (DDS): A private line digital service that offers 2400, 4800, 9600 and 56K bps data rates on an inter-LATA basis by AT&T and on an intra-LATA basis by the BOCs.
Glossary E E&M: A telephony trunking system used for either switch-to-switch, or switch-to-network, or computer/telephone system-toswitch connection. EIA: The Electronics Industries Association is a trade organization in Washington, DC that sets standards for use of its member companies. (See RS-232, RS-422, RS530.) Encapsulation: A technique used by network-layer protocols in which a layer adds header information to the protocol data unit from the preceding layer.
Glossary Foreign Exchange Office (FXO): provides local telephone service from a CO outside of (“foreign” to) the subscriber’s exchange area. In simple form, a user can pick up the phone in one city and receive a tone in the foreign city. Connecting a POTS telephone to a computer telephony system via a T1 link requires a channel bank configured for the FX connection. To generate a call from the POTS set to the computer telephony system, a FXO connection must be configured.
Glossary Internet Protocol (IP): A protocol used to route data from its source to its destination in an Internet enviroment. The Internet Protocol was designed to connect local area networks. Although there are many protocols that do this, IP refers to the global system of interconnecting computers. It is a highly distributed protocol (each machine only worries about sending data to the next step in the route).
Glossary Local Exchange Carrier (LEC): The local phone company which provides local (i.e., not long distance) transmission services. AKA “telco”. LECs provide T1 or FT1 access to LDCs (unless the T1 circuit is completely intra-LATA). Inter-LATA T1 circuits are made up of a combination of Access and Long Haul facilities. Local Management Interface (LMI): A specification for frame relay equipment that defines status information exchange.
Glossary Office Channel Unit - Data Port (OCU-DP): The CO channel bank used as the interface between the customer’s DSU and the channel bank. Off-hook: The condition of a device which has accessed a phone line (with or without using the line). In modem use, this is equivalent to a phone handset being picked up. Dialing and transmission are allowed, but incoming calls are not answered. Contrast “on-hook”.
Glossary Private Branch Exchange (PBX): A phone exchange located on the customer’s premises. The PBX provides a circuit switching facility for phone extension lines within the building, and access to the public phone network. See also “Exchange”. PROM (Programmable Read Only Memory - pronounced “prom”): A permanent memory chip that can be programmed or filled by the customer after by the manufacturer has set initial values. Contrast with ROM. Protocol: 1.
Glossary Robbed Bit Signaling: The popular T1 signaling mechanism where the A and B bits are sent by each side of the T1 termination and are “buried” in the voice data of each voice channel in the T1 circuit. Since the bits are “robbed” infrequently, voice quality remains relatively uncompromised. See “bit robbing”. The robbed-bit signaling technique is used in D4 channel banks to convey signaling information.
Glossary Synchronous Data Link Control (SDLC): A discipline conforming to subsets of the Advanced Data Communications Control Procedures (ADCCP) of the American National Standards Institute (ANSI) and High-level Data Link Control (HDLC) of the International Organization for Standardization, for managing synchronous, code-transparent, serial-by-bit information transfer over a link connection. Transmission exchanges may be duplex, or half-duplex over switched or nonswitched links.
Glossary Transmission Control Protocol (TCP): A communications protocol used in Internet and in any network that follows the US Department of Defense standards for internetwork protocol. TCP provides a reliable host-to-host protocol between hosts in packet-switched communications networks and in interconnected systems of such networks. It assumes that the Internet protocol is the underlying protocol.
