Chapter 4 - ProxyServer Software
ProxyServer User Guide Introduction This chapter describes the ProxyServer software and explains how to make changes to the configuration of your ProxyServer. The major configuration parameters were established during the loading of the software (Chapter 3). The ProxyServer software and configuration utilities allow you to make changes to that initial configuration. The ProxyServer software allows you to refine your configuration based on your network connections.
Chapter 4 - ProxyServer Software Proxy Setup All changes to your ProxyServer configuration are initiated through the Proxy Setup dialog box or Main menu. To view or change your ProxyServer configuration in Windows 98/95 and Windows NT, click Start | Programs | ProxyServer 2.10 | ProxyServer Configuration. You can also start the ProxyServer Configuration from My Computer by double-clicking the Proxy.210 folder on your local drive, then double-clicking on the Roucon.exe file.
ProxyServer User Guide Changing IP Parameters The IP Setup dialog box displays the IP addressing for your LAN and WAN ports that were established during your initial configuration. The IP Setup dialog box allows you to change any of the original parameters. The IP Setup dialog box displays the unique LAN address and net mask you established during your initial configuration.
Chapter 4 - ProxyServer Software The Domain Name Server (DNS) group is used to resolve Fully Qualified Domain Names (FQDN) to an IP address. This field can either be filled in or left blank. If it is left blank, your ISP will assign a DNS address. This DNS address will also be handed off to any client obtaining an IP address from the ProxyServer’s DHCP Server. The Primary Server field defines the IP address of the first host that the ProxyServer will attempt to connect to upon a user request.
ProxyServer User Guide The Static Routes Setup dialog box is displayed. Select and key in the appropriate information for setting up the static route. Port is the type of port, usually LAN (If you have a modem connected to one of the WAN ports and are using it for RAS, you could set up a static route to route incoming traffic to a different network) . The IP Address must be the address of the target host or network in the static route (In our example, Static Route IP Address 200.1.1.
Chapter 4 - ProxyServer Software Changing WAN Port Parameters The ProxyServer is designed to provide the flexibility needed to meet today’s application needs. The WAN Setup dialog provides the controls for WAN configuration. Each WAN port can be configured independently of the others, or they can be combined depending on your application needs.
ProxyServer User Guide Dynamic Bandwidth Allocation The ProxyServer uses a technology called Dynamic Bandwidth Allocation on its WAN ports which allows users to make use of the maximum bandwidth available during application use. In essence, this feature allows a single user to access all three WAN ports simultaneously, allowing maximized bandwidth when using a multiple stream application such as a Web browser.
Chapter 4 - ProxyServer Software Modem 3 Modem 2 Internet Modem 1 Web Page Elements LINK3 LINK2 LINK1 ETHERNET COMMAND POWER ON 10BASET OFF 10BASE2 MTPSR3-200 Hub Workstation A Running Web Browser (IP Address 192.168.2.4) Workstation C Running Telnet Session (IP Address 192.168.2.2) Workstation B Running FTP Session (IP Address 192.168.2.3) If one or both of the sessions on WAN 2 and 3 end, the ProxyServer reallocates the newly available bandwidth to the Web browser.
ProxyServer User Guide Example 3 - Single WAN Port Dedicated to Manager In this example, a single WAN port (WAN 1) has been dedicated for exclusive use by a manager workstation (IP address 192.168.2.4). This is done by restricting all other employee workstations to either WAN 2 or WAN 3. The end result is that the manager workstation has exclusive access to WAN 1 (meaning @ 50 Kbps bandwidth automatically), plus the benefit of added bandwidth if WANs 2 and 3 are available or have “spare” bandwidth.
Chapter 4 - ProxyServer Software Similarly, the dialog box below shows the WAN 3 tab with the IP addresses of the Sales workstations restricted only to the WAN 3 port.
ProxyServer User Guide MLPPP The ProxyServer supports Multi-Link Point-to-Point Protocol (MLPPP) on its WAN ports. This protocol allows the three WAN ports to act as a single pipeline using only one IP address to provide maximum bandwidth. Applications such as Telnet, FTP, and Web browsers can run a single session out of the ProxyServer and achieve up to 150K of bandwidth depending on line conditions.
Chapter 4 - ProxyServer Software Once MLPPP is enabled, you need to configure the individual WAN ports. The WAN 1, WAN 2 and WAN 3 tabs allow you to configure the individual ports for separate use (i.e., non-MLPPP) or in bonded use, as with MLPPP. Select each tab, and enter the identical User Name, Password, and Dial Number for each port. Once this is done, click OK and you will be returned to the Proxy Setup dialog box. Enabling MLPPP also affects the WAN Setup dialog.
ProxyServer User Guide Port Type The Port Type group (in the WAN Setup dialog) is used to configure the ports for specific applications. The default settings for this group are Dial Out only and Proxy Enable. This default setting works if you are setting up the WAN port to communicate with the Internet. If this is the case, the WAN port must be enabled and the Port Type group configured for Dial Out Only or Dial Out/In and the Proxy Enable option selected.
Chapter 4 - ProxyServer Software Changing Internet Parameters The Internet Setup dialog box displays the phone number the ProxyServer is going to dial to reach your ISP, the protocol the ISP supports, MultiLink Point-to-Point Protocol (MLPPP) option, and if you would link the ProxyServer to dial a telephone when you power on your unit. The Dial Number field displays the phone number of the ISP you initially assigned during your initial configuration.
ProxyServer User Guide Protocol) messages. These messages can be useful as troubleshooting tools; however, it is recommended that under normal circumstances all items should be disabled to avoid degradation of ProxyServer performance. The ProxyServer is capable of performing MultiLink Point-to-Point Protocol (MLPPP). MLPPP provides the opportunity for greater bandwidth by bundling WAN port links. Check MultiLink PPP (MLPPP) to enable this option if your ISP provides this support.
Chapter 4 - ProxyServer Software Enabling the DHCP Server The Multi-Tech DHCP (Dynamic Host Configuration Protocol) server feature manages all IP address assignments within a local/private LAN. The DHCP Server maintains a list of available IP addresses and when a client computer asks for one, the DHCP Server sends the IP Address to the client. The client computer, configured with that information, can then participate in the TCP/IP network.
ProxyServer User Guide Adding ProxyServer Applications The Proxy Applications configuration dialog box allows the ProxyServer systems administrator to configure the set of applications available for proxying by the ProxyServer. Click the ProxyServer button in the Proxy Setup menu to display the Proxy Applications configuration dialog box which lists all the applications currently supported by the ProxyServer.
Chapter 4 - ProxyServer Software The ProxyServer administrator can set up “filters” on the proxy server for better control. The Filter option 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 to exclude packets of a particular protocol or any particular field in a LAN packet.
ProxyServer User Guide Enabling the Virtual Server The virtual server feature of the ProxyServer allows you to have multiple servers on your local area network (LAN) with one static IP address (from your ISP or Multi-Tech’s Global Dynamic WAN Addressing) assigned to each WAN port. A normal internet connection requires a static IP address for each server on your LAN. A normal Internet connection is shown in the following illustration. Internet Router Hub Firewall 204.111.2.
Chapter 4 - ProxyServer Software address to each of the ProxyServer’s WAN ports and then map your servers to that WAN port address the same way you would map a static IP address from your ISP. The predefined Global Dynamic WAN port addressing scheme is 0.0.0.1 for WAN port 1, address 0.0.0.2 for WAN port 2, and 0.0.0.3 for WAN port 3. If MLPPP is being used, you can assign 0.0.0.0 to all three WAN ports.
ProxyServer User Guide the Internet by functionality. The addresses that we assigned to our servers in the virtual server example are unregistered addresses that are only seen by the ProxyServer. These local IP addresses are arbitrarily assigned to servers in our virtual server connection example. For example, we assigned IP address of 192.168.11.20 to the FTP server, 192.168.11.30 to the Web server, 192.168.11.40 to the e-mail server, and 192.168.11.50 to the MultiVOIP.
Chapter 4 - ProxyServer Software Enabling Remote Servers The Applications Setup dialog box lets you set up support for Telnet Server, TFTP (Trivial File Transfer Protocol), WEB Server, and Dumb Terminal Management in the ProxyServer. Telnet/TFTP Telnet is an applications level protocol commonly found in IP-based networks that allows terminal emulation at a remote workstation. To do this, there is usually a server at a central point that allows multiple clients to connect and request to use the service.
ProxyServer User Guide Click the word “Login” to launch the ProxyServer Configuration program. The Enter Network Password dialog box is displayed. Type the term “supervisor” in the User Name field (no password is needed) and click OK. The Proxy Server Configuration menu is displayed. The Proxy Server Configuration menu provides several categories: Protocol Stacks, Device Drivers, Other Setup, and Statistics for each of the WAN ports.
Chapter 4 - ProxyServer Software Running Diagnostics The ProxyServer Setup program lets you perform various hardware tests on the LAN and WAN links. The Diagnostics dialog box is displayed by clicking the Built in Test button in the ProxyServer Setup dialog box. Diagnostic tests are performed if the Communication type of the Local Port configuration is set to COM Port. If the Local Port configuration is set for IP, no diagnostic tests are performed by the ProxyServer.
ProxyServer User Guide Running Statistics The Statistics dialog box allows you to view the real-time WAN statistics for the ProxyServer. This includes a list of the available WAN ports, the state of the attached modems, and the current baud rates. To view details of a specific port, double-click the entry in the Port list or highlight the entry and click Details. The Port Statistics dialog box provides information relating to the traffic on the ProxyServer’s WAN port.

Appendices Appendix E - 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.
ProxyServer User Guide 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. The Application Layer protocols are examples of common TCP/IP applications and utilities, which include: 110 • Telnet (Telecommunication Network): a virtual terminal protocol allowing a user logged on to one TCP/IP host to access other hosts on the network, described in RFC 854 ( ftp:// ds.internic.net/rfc/rfc854.txt).
Appendices 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
ProxyServer User Guide A Access: The T1 line element made up of two pairs of wire that the telephone 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 56 Kbps leased (private) line service. Similar to services of MCI and Sprint. ASDS is available in nx56/64 Kbps, 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 64 Kbps and one Dchannel at 64 Kbps (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).
ProxyServer User Guide 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 Data Link Connection Identifier (DLCI): One of the six components of a frame relay frame. Its purpose is to distinguish separate virtual circuits across each access connection. Data coming into a frame relay node is thus allowed to be sent 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.
ProxyServer User Guide 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.
ProxyServer User Guide 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.
ProxyServer User Guide 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 telephone handset being picked up. Dialing and transmission are allowed, but incoming calls are not answered. Contrast “on-hook”.
Glossary Private Branch Exchange (PBX): A telephone exchange located on the customer’s premises. The PBX provides a circuit switching facility for telephone extension lines within the building, and access to the public telephone 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.
ProxyServer User Guide Routing Information Protocol (RIP): A distance vector-based protocol that provides a measure of distance, or hops, from a transmitting workstation to a receiving workstation. RS232-C: An EIA standard for a serial interface between computers and peripheral devices (modem, mouse, etc.). It uses a 25-pin DB-25, or a 9-pin DB-9 connector. The RS-232 standard defines the purposes, electrical characteristics and timing of the signals for each of the 25 lines.
Glossary T Tariff: The rate/availability schedule for telephone and ISDN services from a regulated service provider. TCP/IP: A set of communication protocols that support peer-to-peer connectivity functions for both local and wide area networks. T Carrier: The generic name for a digitally multiplexed carrier system. In the North American digital hierarchy, a T is used to designate a DS (digital signal) level hierarchy. Examples: T1 (DS1) is a 1.544 M bps 24-channel designation. In Europe, T1 is called E1.
ProxyServer User Guide Transport Protocol Data Unit (TPDU): A transport header, which is added to every message, contains destination and source addressing information that allows the end-to-end routing of messages in multi-layer NAC networks of high complexity. They are automatically added to messages as they enter the network and can be stripped off before being passed to the host or another device that does not support TPDU’s. Trunk: Transmission links that interconnect switching offices.
