Chapter 4 - ProxyServer Software
DSU 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 | Proxy Server 2.10 | Proxy Server Configuration. You can also start the Proxy Server setup from My Computer by double-clicking the Roucon (or Roucon.exe) icon in the Proxy.210 folder on your local drive.
DSU ProxyServer User Guide Changing IP Parameters The IP Setup dialog box displays the IP addressing established during initial configuration for your LAN and WAN ports. This dialog box enables you to change any of the original parameters as necessary. LAN The IP Setup dialog box displays the unique LAN address and net mask you established during initial configuration.
Chapter 4 - ProxyServer Software DHCP The DHCP (Dynamic Host Configuration Protocol) group allows IP addresses to be assigned by a DHCP Server. In such cases, a PPP client connected to WAN port 2 will be on the same IP network as the LAN port. Because the DHCP Server automatically assigns an IP Address for a PPP client coming up on a “Client Only” WAN port, this feature can save IP addresses that otherwise would have been taken up by the WAN port.
DSU ProxyServer User Guide Local PC Local PC IP Address - 192.168.2.10 Subnet mask - 255.255.255.0 Default Gateway - 192.168.2.6 Internet MTPSR2-201 Client PC Remote Network RS232/V.35 56K DSU 10BASET COMMAND POWER ON OFF MTPSR2-201 Hub Router T1, Frame Relay, V.90/K56Flex, ISDN Router Hub IP Address - 192.168.2.6 Subnet mask - 255.255.255.0 Client PC Router Router Static Route IP Address - 200.1.1.10 Subnet mask - 255.255.255.0 Default Gateway - 200.1.1.1 IP Address - 200.1.1.
Chapter 4 - ProxyServer Software Port refers to the type of port - LAN, in our current example. If you have a modem connected to WAN 2 and are using WAN 2 for RAS, you can set up a static route to send incoming traffic over to a different network. The IP Address must be the address (in dotted decimal form) of the target host or network in the static route. (In our example, Static Route IP Address 200.1.1.0 indicates that PC clients on routers with IP addresses beginning with “200.1.
DSU ProxyServer User Guide 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. Beyond the basic controls offered in the Mode and Connection Method groups (described in detail in your Help system) the WAN Setup menu includes many advanced features.
Chapter 4 - ProxyServer Software Link Usage Control Group Note: The Link Usage Control Group is not active for WAN 1 (DSU) and is not supported for MLPPP. The Link Usage Control group allows you to control the conditions and parameters of the traffic on WAN port 2 only. Using the Enable and Idle Time features, you can cause the ProxyServer to drop the connection on WAN port 2 after a specified duration without activity (as defined in the Idle Time field).
DSU ProxyServer User Guide 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 the ISP’s phone number when you power on your unit. The Dial Number field displays the phone number of the ISP you assigned during initial configuration.
Chapter 4 - ProxyServer Software 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.
DSU ProxyServer User Guide The master control for MLPPP is on the right-hand side of the dialog box, and the default setting is disabled (unchecked). To implement MLPPP, first enable (check) the MultiLink PPP (MLPPP) option. Once MLPPP is enabled, you need to configure the individual WAN ports. The WAN 1 and WAN 2 tabs allow you to configure the individual ports for separate use (i.e., non-MLPPP) or in bonded use, as with MLPPP.
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.
DSU ProxyServer User Guide Adding Proxy Server 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 Proxy Server 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 ProxyServer for better network 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.
DSU ProxyServer User Guide Enabling Virtual Servers The virtual server feature of the ProxyServer enables you to have multiple servers on your local area network (LAN) with one static IP address. A normal Internet connection requires a static IP address for each server on your LAN. A normal Internet connection is shown in Figure 4-4. Internet Router Hub RD TD CL LK RD TD CD NS DS RD TD CD V35 Firewall 204.111.2.60 Secure LAN FTP Server 204.111.2.20 Web Server 204.111.2.30 Figure 4-4.
Chapter 4 - ProxyServer Software addresses the same way you would map a static IP address from your ISP. The predefined Dynamic WAN port addressing scheme is 0.0.0.1 for WAN port 1 and address 0.0.0.2 for WAN port 2. If MLPPP is being used, you can assign 0.0.0.0 to both WAN ports. You can dynamically map one Global Dynamic address to either WAN port on the ProxyServer and statically map the other WAN port. Internet WAN Port Static IP Address 204.111.2.99 RS232/V.
DSU ProxyServer User Guide With static IP addressing, the Global IP Address is the IP address that is seen by the Internet. This global address will be used by the virtual server feature to filter (by functionality) the activity of the traffic to and from the Internet. The addresses we assigned to our servers in the virtual server example are unregistered addresses that are seen only by the ProxyServer. These local IP addresses are arbitrarily assigned to servers in our virtual server connection example.
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. Initially, all four server types are enabled (or checked). The Server Password field enables the user to assign a password that must be entered along with the “supervisor” default logon name.
DSU ProxyServer User Guide WEB Server The Web Server interface enables you to use your Web browser to configure the ProxyServer remotely on your local network. Enter the IP address of the ProxyServer in the Location (Address) field of your browser to launch the Multi-Tech Proxy Server Configuration site.
Chapter 4 - ProxyServer Software Running Statistics The Statistics dialog box enables you to view the real-time WAN statistics for the ProxyServer. This includes a list of the available WAN ports, the state of any attached modems, and the current baud rates. To view the details for 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.
DSU ProxyServer User Guide Running Diagnostics The ProxyServer is equipped with a built-in diagnostics utility that can be accessed through the COM port of your PC (remote users cannot access diagnostics). Click Built-in Test in the Proxy Setup menu and the Diagnostics dialog is displayed. In the Test Port group (Ethernet, WAN 1 or WAN 2), select the port where you want to run diagnostics, install the appropriate loopback plug on that port, then click Test to start the test.

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 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. Foreign Exchange Station (FXS): See FX, FXO. To generate a call from the computer telephony system to the POTS set, an FXS connection must be configured.
DSU ProxyServer User Guide data to the next step in the route). Internetwork Packet Exchange (IPX): A NetWare communications protocol used to route messages from one node to another. IPX packets include network addresses and can be routed from one network to another. An IPX packet can occasionally get lost when crossing networks, thus IPX does not guarantee delivery of a complete message. Either the application has to provide that control, or NetWare’s SPX protocol must be used.
Glossary 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. Local Loop: A transmission path, typically twisted-pair wire, between an individual subscriber and the nearest public telecommunications network switching center. The wires provide ISDN service, but require an NT1 at the user end and an LT at the network end. (AKA, “loop” or “subscriber loop”.
