Introduction
Welcome to Multi-Tech’s new ProxyServer 200-Series, model MTPSR1-202ST, a single, secure
gateway that provides multiple LAN users with high performance Internet access. The ProxyServer
functions as a TCP/IP proxy server that resides on the outer edge of your firewall and provides Basic
Rate ISDN Service using its internal 2B+D terminal adapter. The MTPSR1-202ST supports dial in
Remote Access Server (RAS), RAS Dial-Out Redirector, and can act as an asynchronous Gateway .
The MTPSR1-202ST ProxyServer features a 10Base-T port for local LAN connection, Command
Port for configuration, and an internal 2B+D ISDN terminal adapter for 64 Kbps per channel or 128
Kbps effective bandwidth when software BONDing (Bandwidth ON Demand) using ML-PPP is
employed. BONDing starts with 64K and when a certain threshold is reached, the second 64K
channel is brought up and bonded.
The MTPSR1-202ST supports client and site filtering, dial-in remote access from a PPP client,
includes Network Address translation (NAT) allowing corporate web, FTP, and mail servers access
from the Internet, dials on-demand for link establishment as Internet services are requested, and
handles HTTP, FTP, POP3, DNS, NNTP, TFTP, IRC, SMTP, Gopher, Finger , rlogin, and Citrix
requests.

ProxyServer User Guide
Front Panel
The front panel of the ISDN ProxyServer contains three groups of LEDs that provide the status of the
Ethernet LAN connection, the ISDN WAN connection, and the general status of the ProxyServer (Fail
and Power).
The Ethernet LAN LEDs display the activity of the LAN if the ProxyServer is connected to the LAN,
transmitting or receiving packets, and if a collision is occurring. The ISDN LEDs, or WAN port LEDs,
display the status of the port and show if the link is ready to transmit or receive serial data, and if one
or both Bearer Channels are active. The general group of LEDs indicates whether the self test
passed or failed and if the power On/Off switch on the back of the ProxyServer is set to On.

Chapter 3 - Software Loading
and Configuration
ProxyServer User Guide
Introduction
This chapter covers procedures for loading the ProxyServer software from a Windows PC (Win98/95
or WinNT) and configuring your ProxyServer. Configuration includes setting up the LAN and WAN
port IP addresses, setting up the ISDN configuration default parameters, then downloading the
default setup to the target ISDN ProxyServer.
Before You Start Loading your Software
Consider the following choices before you configure your ProxyServer and record your selections on
the following pages; then refer to them while loading your software.
Network Configuration
ü Network Switch Type_________________________________________
Select the network switch type your ISDN service provider uses at its local central office. You can set
the ProxyServer to NET3 (EuroISDN), or 1TR6 (German), AT&T 5ESS, DMS-100, or NI-1. If you do
not know the switch type, you can get the information from your ISDN service provider.
ü Data TEI_____________________________________________________
The Data TEI (Terminal Endpoint Identifier) is assigned to the data channel. Y ou can select “Auto TEI,”
a fixed TEI, number (from 0 to 63), or “Disabled.” A TEI is a number used by the central of fice switch to
uniquely identify each device that is connected to the network. When it uses dynamic TEI assignments
(Auto TEI), the central office switch assigns a TEI each time the ProxyServer connects to the network.
However, the ISDN service provider may assign a fixed TEI at subscription time, in which case you
must configure the ProxyServer with the fixed TEI number . You can also disable the channel, which
may be useful when multiple ProxyServers are attached to a network terminator bus.
ü Voice TEI___________________________________________________
The Voice TEI is the TEI assigned to the voice channel. You have the same choices as for the Voice
TEI: “Auto TEI,” a fixed TEI number (from 0 to 63), or “Disabled.”
ü Data SPID__________________________________________________
The ProxyServer must be configured with the Service Profile Identifier (SPID). The data SPID is
assigned by the local phone company and is for the specific Basic Rate Interface (BRI) line to which
the ProxyServer will be attached. The data SPID string can have up to 20 characters. The data
SPID is not used if the switch type is set to NET3.
Note: For DMS-100 switches, any ASCII character except the underline (_) character is valid. For
NI-1 and AT&T switches, only the digits 0-9 are valid.
ü Voice SPID__________________________________________________
The voice SPID is assigned by the local phone company and is for the specific BRI line to which the
ProxyServer will be attached. The voice SPID string can have up to 20 characters. The data SPID is
not used if the switch type is set to NET3.
Note: For DMS-100 switches, any ASCII character except the underline (_) character is valid. For
NI-1 and AT&T switches, only the digits 0-9 are valid.
ü Data Directory Number________________________________________
The data Directory Number (DN) is a telephone number that is assigned to the ProxyServer at
subscription time by the ISDN service provider. The DN is a string of up to 24 characters; valid
characters are 0-9, the * character, and the # character.
ü Voice Directory Number_______________________________________
The voice Directory Number (DN) is a telephone number that is assigned to the ProxyServer at
subscription time by the ISDN service provider. The DN is a string of up to 24 characters; valid
characters are 0-9, the * character, and the # character.
16
MTPSR1-202ST
Chapter 3 - Software Loading and Configuration
Call Control Parameters
ü Persistent DTR Dialing_______________________________________
A high DTR (Data Terminal Ready) signal on the Command port indicates that your computer or
terminal is ready to communicate with your ProxyServer. DTR normally goes high when a
communication program starts or is ready to dial. Persistent DTR dialing enables the ProxyServer to
automatically redial the number stored in memory location 0 whenever DTR is high and the serial port
does not have an active call. You may enable or disable this feature.
ü Calling Line Identification_____________________________________
Identifies whether the two endpoints of a connection are enabled or disabled. Since RING messages
only appear for ISDN data calls, the CLI feature does not define a means of conveying Calling Party
information to the terminal for ISDN voice calls. The CLI information is only included with the first
RING message for a given incoming call and appears as follows:
RING
FM: 5552000 TO: 5551000
If the Calling Party Number information is not included in the incoming SETUP message, the RING
message appears as follows:
RING
TO: 5551000
If the Called Party Number information is not included in the incoming SETUP message, the RING
message will appear as follows:
RING
FM: 5552000
If neither the Called Party Number, nor the Calling Party Number is included in the incoming SETUP
message, the RING message will contain no additional information.
ü Auto Protocol Detection - Always Unchecked (Disabled)
Identifies that automatic protocol detection is enabled or disabled for an ISDN data call. The default
setting is 0, which disables the Auto-Protocol Detection function.
ü Auto Answer Data Calls ____ __________ Rings to Answer__________
Select Auto Answer if you want your ProxyServer to automatically answer all incoming data calls (this
option does not affect the analog port). The Rings to Answer number, in the range of 1 to 255, selects
the number of rings the ProxyServer waits before answering an incoming call. The default is one ring.
Data Control
ü Data Protocol _______________________________________________
The data protocol, also known as the B-channel protocol and the rate adaption protocol, is the
“language” that is spoken over each 64 Kbps channel between two ISDN devices. The devices on
both ends of the ISDN link must use identical data protocols.
MLPPP Protocol (Not supported on the MTPSR1-202ST)
The MLPPP (Multi-Link PPP) protocol provides rates up to 64 Kbps per channel. This protocol uses
both B channels at once, providing an aggregate data transmission speed of 128 Kbps.
ü Dialing Method _______________________________________________
Select either the “Enbloc” or the “Overlap” dialing method for use when establishing a data call. Your
ISDN service provider determines the dialing method. The en bloc method is used for most ISDN
dialing; however, you can select the overlap method if you are working with a private network.

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. The software is based on a main menu (Proxy Setup) that allows you to consider all
the parameters for a particular feature (e.g., Internet access, DHCP Server addressing, and
Virtual Server mapping). These features, along with others are discussed in detail in the
ProxyServer Configuration section later in this chapter.
The other five configuration utilities offer additional functionality. Wizard Setup guides you
through the initial configuration and software downloading, as described in Chapter 3. Download
Firmware allows you to download new versions of firmware when enhancements become
available. The Configuration Port Setup utility allows you to change the method by which you
access the ProxyServer (i.e., direct connection of a PC to the Command Port on the ProxyServer,
or via your network connection to the LAN port on the ProxyServer). The Uninstall ProxyServer
Configuration utility is designed to remove the software from your PC. The WAN Device
Configuration utility will open the Print Console, a terminal emulation program that will enable
you to configure any external devices connected to the WAN ports. The Remote User Data Base
option allows you to enter information regarding your remote users; and, the Upgrade Proxy
feature allows you to download software updates from Multi-Tech System’s FTP site.
Note: The WAN Device Configuration utility is only supported if you are directly connected to
the ProxyServer. This Utility is not supported when accessing the ProxyServer via the network.
Your ProxyServer software includes the ProxyServer on-line Help system. The Help is designed
to be context sensitive. Clicking the Help button within a given dialog will provide definitions and
recommended values for each button, option, and field for that dialog. In some instances, you will
also be presented with a list of related topics that can be displayed by clicking the green,
underlined text. In addition, you can search the entire Help system (via the Index tab) for
definitions and references to specific terms, fields, and recommended values where applicable.
Before You Begin
The ProxyServer software operates in a Microsoft Windows environment. Your ProxyServer
program group contains all of the utilities described above, and is accessible in Windows by
clicking Start | Programs | ProxyServer 2.10 | (utility), or by double-clicking the utility icon in the
program group in My Computer. The program group is shown here:

MTPSR1-202ST
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. After loading, the Proxy Setup menu will appear.
Chapter 4 - ProxyServer Software
The Proxy Setup menu consists of 13 buttons, eleven of which allow you to display and change the
IP settings, define the WAN ports, change features such as the Internet, DHCP Server, ProxyServer,
and virtual Servers, display WAN port Statistics, control activation of Telnet, TFTP, and WEB servers
and dumb terminal management, test the communications link, print messages received from the
target ProxyServer, and download setup information to the ProxyServer.
The two outer buttons in the bottom row enable you to open the on-line Help system and end (Exit) a
Proxy configuration session.
Note: Pressing the Built-In T est button displays the Diagnostics dialog box which allows you to
perform certain hardware tests on the LAN and WAN links. The Print Console option brings up the
console terminal that displays any print message received from the ProxyServer.

ProxyServer User Guide
Changing IP Parameters
The IP Setup dialog box displays the IP addressing for your LAN and W AN 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. If you are using your ProxyServer in an Internet application with one or more of
the WAN ports connected to the Internet and your ISP is dynamically assigning addresses to those
WAN ports, then you will want to leave the ISP Assigns Dynamic Address option active.
If you wanted to change a WAN port to support a static IP address, you would select the WAN port
and disable the ISP Assigns Dynamic Address option. This activates the IP Address and Net Mask
fields for that WAN port. You then need to enter a static IP address in the IP Address field and
assign an appropriate net mask in the Net Mask field. Then you would want to check the WAN Setup
dialog box and establish the Port Type for the selected WAN port, e.g., if the WAN port is being used
for remote access, you would want to enable the RAS Enable option; if the port is being used as a
dial in feature, you would want to enable the Dial in Only option in the Port T ype group.
If you wanted to change a WAN port to dial out to a telephone number other than the Internet, you
would select the WAN port and disable the ISP Assigns Dynamic Address option. This activates
the IP Address and Net Mask fields for that WAN port. You then need to enter a WAN port IP address
in the IP Address field and assign an appropriate net mask in the Net Mask field. You would then
need to check the WAN Setup dialog box and change the Port Type for the selected WAN port to
enable the Dial Out option and enable the Asynchronous Gateway (AG Enable) option.
If you wanted to change a WAN port to be available for remote access, you would select the WAN
port and disable the ISP Assigns Dynamic Address option. This activates the IP Address and Net
Mask fields for that WAN port. You then need to enter a WAN port IP address in the IP Address field
and assign an appropriate net mask in the Net Mask field. You would then need to check the WAN
Setup dialog box and change the Port T ype for the selected WAN port to enable the Dial In option
and enable the Remote Access Server (RAS Enable) option.
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 the WAN port 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.
To enable DHCP, you must check the Client box and enter the IP address of the external DHCP
Server (e.g., Microsoft’s DHCP feature) in the Server Address field. The Server Address is assigned
by your systems administrator.

MTPSR1-202ST
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. If this server is unavailable, the ProxyServer will attempt a
connection with the Secondary Server (if defined). The Secondary Server field defines the IP
address of the DNS server for cases where the primary server is unavailable.
The Static Routes feature allows a remote client PC access to the Internet through a pre-defined
route (static route). Static routing is normally used when a part of an internetwork can only be
reached by 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. In the
example below, a data packet sent from the remote client PC to access the remote Internet through
the MTPSR1-202ST must have IP Address 200.1.1.0 and Gateway Address 192.168.2.1 (entered as
the Static Route configuration). This determines the return path the data packet will take back to the
client PC.

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 the WAN port 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 200.1.1.0 indicates that PC clients on Routers with IP addresses beginning with
200.1.1 will be included on the static route). The Address Mask is the IP subnetwork mask
(255.255.255.0) of the target host. The Gateway Address must be the IP address of the local router
(Gateway Address 192.168.2.1) on the next hop toward the target host and the port (i.e., LAN) with
which it is associated. Metric is the hop count (1) to the target host.
Once you have completed entering all the appropriate information, click OK. The static route is
entered in the Static Routes table.

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. The basic controls offered in the
Mode and Connection Method groups are described in detail in your on-line Help system. The Link
Control (Dial-on-demand) and Advanced tab are discussed in some detail.
Chapter 4 - ProxyServer Software
The Link Control group allows you to control the conditions and parameters of the traffic on the
WAN port. Using the Enable and Idle Time features, you can cause the ProxyServer to drop the
connection on the selected WAN port after a specified duration without activity (as defined in the Idle
Time field). The default setting is enabled (checked) with an idle time of 10 minutes. If you do not
wish to use this option, click to disable (uncheck) it.
The Port T ype 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. As mentioned earlier, the Internet Setup dialog
box is used to configure the Internet Link Control Protocol, i.e., call connection and handshaking.
The Asynchronous Gateway (AG Enable) feature can be used on WAN ports configured as Dial Out
only or Dial Out/In. This feature is used to enable the ProxyServer to have a port available for a
remote user running a communications package to gain access to an available port on the
ProxyServer and dial out. When you enable this feature the Asynchronous Gateway group (at the
bottom of the dialog) becomes active. Refer to the on-line Helps for a description of features in this
group.
The WAN ports can also be configured for remote access (RAS Enable) with either the Dial In Only
or Dial Out/In option enabled. If enabled, you must enable Remote Access and enter the WAN port
IP address in the IP Setup dialog box. This ensures that the selected WAN port and the Remote
Address assigned to it are in the same LAN segment. The remote IP address is assigned to the
remote user.

From the Advanced tab, you can change the parameter configurations for the type of Message
Printing, determine when to enable Script Printing, and define the Switch T ype providing the ISDN
connection.
In the Configuration T ypes window, select the appropriate configuration (e.g., USA_DMS100) and
click Edit. The Parameter Configuration dialog box is displayed.
This dialog box displays the network switch type and the US Parameters or the Europe Parameters,
depending on the switch type selected. In the first example (above), the default US Parameters are
displayed and are available for editing purposes. The uppermost text box (USA_DMS10) on the
dialog box is not available for editing as it is used only for adding the names of new parameter
configurations. The Net Switch Type is also unavailable as it is the switch type that was defined for
this particular configuration.
General Parameters
Data TEI (Terminal Endpoint Identifier) - You may have received a fixed TEI (a number from 0 to 63)
from your provider; if so, then select that number from the list in the Data TEI box. However , if the
central office switch assigns a dynamic TEI each time your ProxyServer connects to the network,
then leave it set to the default, “Auto TEI.” If you have multiple ProxyServers attached to a network
terminator bus, you may want to set the Data TEI to ”Disabled.”
V oice TEI - Y ou may have received a fixed TEI (a number from 0 to 63) from your provider; if so, then
select that number from the list in the Voice TEI box. However, if the central office switch assigns a
TEI each time your ProxyServer connects to the network, then leave it set to “Auto TEI.” Again, if
you have multiple ProxyServers attached to a network terminator bus, you may want to set the Voice
TEI to “Disabled.”

V oice SPID - Enter the Voice SPID, if required, that was assigned by the local phone company for
the specific BRI line to which the ProxyServer is attached. The V oice SPID string can have up to 20
characters. For DMS-100 switches, any ASCII character except the underline (_) is valid; For NI-1
and AT&T switches, only the digits 0-9 are valid.
Data Directory Number (DN) - The data DN is a telephone number the ISDN service provider
assigns, if required, to the ProxyServer at subscription time; this can be a string of up to 24
characters. V alid characters are 0-9, the * character, and the # character.
V oice DN - The voice DN is a telephone number the ISDN service provider assigns, if required, to the
ProxyServer at subscription time; this can be a string of up to 24 characters. V alid characters are 0-9,
the * character, and the # character.
European Parameters
The Europe Parameters group includes the Data ISDN, Voice ISDN, the Data Sub Address, and the
voice Sub Address. The Data and Voice ISDNs and Sub Addresses may not be required by your
service provider. If the ISDNs and Sub Addresses are required, the fields are defined below.
Data ISDN - Enter the Data ISDN, if required, that was assigned by the local phone company for the
specific BRI line to which the ProxyServer is attached. The Data ISDN string can have up to 20
characters. If the switch type is NET3, the Data ISDN is not used.
V oice ISDN - Enter the Voice ISDN, if required, that was assigned by the local phone company for the
specific BRI line to which the ProxyServer is attached. The V oice ISDN string can have up to 20
characters. If the switch type is NET3, the Voice ISDN is not used.
Data Sub Address - The Data Sub Address is a telephone number the ISDN service provider
assigns, if required, to the ProxyServer at subscription time; this can be a string of up to 24
characters. V alid characters are 0-9, the * character, and the # character.
V oice Sub Address - The Voice Sub Address is a telephone number the ISDN service provider
assigns, if required, to the ProxyServer at subscription time; this can be a string of up to 24

ProxyServer User Guide
Call Control Parameters
Persistent DTR Dialing - Data Terminal Ready (DTR) normally goes high when a communication
program starts or is ready to dial. A high DTR on the serial port indicates that your computer or
terminal is ready to communicate with the ProxyServer. The Persistent DTR Dialing function built into
the ProxyServer enables the ProxyServer to automatically redial the telephone number of the ISDN
service provider whenever DTR is high and there is no active call on the serial port. You can either
enable or disable this feature (the default for this function is “disabled” or unchecked).
Note: You can use the key combination, “Alt-P” to check or uncheck this function.
Calling Line Identification (CLI) - When you check this function, the ProxyServer identifies (for
ISDN data calls only) whether the two endpoints of a connection are enabled or disabled for the
purposes of RING messages. If the Calling Party Number is included in the incoming SETUP
message for a given call, the RING message will display it, together with the Called Party Number, in
the following format: “FM: 5552000 TO: 5551000.” If the Called Party Number is not included in the
SETUP message, the RING message will show only the Calling Party Number as follows: “FM:
5552000.” If neither number is included, the RING message will contain no additional information.
The default for this parameter is “enabled” or checked. Note: you can use the key combination
“Alt-D” to check or uncheck this function.
Auto Protocol Detection - You should leave this function disabled (unchecked) because we set the
Data Protocol in the Data Control group to “MLPPP” and do not use any of the other protocols listed
there.
Auto Answer Data Calls - You can enable this function if you want your ProxyServer to answer
automatically all incoming data calls (this option does not affect the analog port). If you do enable the
Auto Answer function, you should also set the Rings To Answer function unless you want to leave it at
the default selection which is one ring before it answers. (Selecting either “0” or “1” causes it to
answer after the first ring.)
Data Control
Data Protocol - As mentioned above (in Auto Protocol Detection), we leave this function set to
MLPPP, which uses both B channels (each at rates of up to 64 Kbps per channel) providing an
aggregate data transmission speed of 128 Kbps, maximum.
Data Compression - You should leave this function set to the default, which is “None.”
Dialing Method - The default is “Enbloc,” which is used for most ISDN dialing; however, if your
ProxyServer is on a private network you can switch to the “Overlap” dialing method for establishing a
data call on the ISDN line.

MTPSR1-202ST
Internet Setup
The Internet Setup dialog box displays the phone number the ProxyServer is going to dial to reach
your ISP, the protocol the ISP supports, and if you would link the ProxyServer to dial a telephone
when you power on your unit.
Chapter 4 - ProxyServer Software
The Dial Number field displays the phone number of the ISP you initially assigned during your initial
configuration. If the WAN port is not being used for Internet access, then the Dial Number field should
be blank.
ProxyServer supports Point-to-Point Protocol (PPP) and Serial Line Internet Protocol (SLIP) on the
WAN link. The majority of the time the ISP is going to support PPP. PPP supports two user
authentication protocols; Password Authentication Protocol (PAP) and Challenge Handshake
Authentication Protocol (CHAP). When you established your Internet account your ISP should have
indicated which protocol it supports.
Your user name and password are displayed in the PPP group for the WAN port which will be
connected to the Internet. The user name and password were enterred in the Default WAN Link
setup dialog box during the initial configuration. If the WAN port is not being used for Internet access,
then the User Name and Password fields will be blank. You can change your User Name and
Password in these fields for the WAN port.
Clicking the Advanced tab brings up the parameters that affect the WAN link.

The Message Printing Control group is used to flag specific items for generating messages on
various conditions, including Printing, Alarm, NCP (NetWare Core Protocol), and LCP (Link Control
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.
If the Need to dial out initially option is enabled (default) the ProxyServer will dial the phone
number entered in the Dial Number window upon start up. If this option is disabled, then the
ProxyServer will wait to dial until the first dial request has been made.
The Echo Request group allows you to configure the Link Control Protocol (LCP) Echo Request
parameters. Options include Maximum Number of unacknowledged LCP Echo requests allowed
before triggering the termination of the link to the peer (valid range is 1 to 20 with a default of 6
requests) and Send Interval defines the interval that the LCP will insert between two consecutive
LCP Echo Requests (valid range is 0 to 65535 with a default 0 seconds).
The Termination Request group allows you to configure the Link Control Protocol (LCP) Termination
Request parameters. Options include Maximum Number of LCP Termination Requests issued after
the completion of a back-off interval (valid range is 1 to 20 with a default of 10 requests); and, Send
Interval Max defining the interval that the LCP will insert between two consecutive LCP Termination
Requests (valid range is 5 to 65535 with a default of 5 seconds).
The Configurations Requests group allows you to configure the Link Control Protocol (LCP)
Configuration Request parameters. Options include Maximum Number of requests to be sent before
backing off due to no response (valid range is 3 to 65535 with a default setting of 6 requests); Send
Interval Max defining the interval between two consecutive LCP configuration requests (valid range is
5 to 65535 with a default of 5 seconds); and, Backoff Interval defining the interval that the LCP will
insert once the unanswered Maximum Number of Configuration requests has been reached (valid
range is 5 to 65535 with a default of 5 seconds).

MTPSR1-202ST
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.
What are the advantages of DHCP? Why not let your systems administrator assign permanent IP
addresses? Because DHCP assigns IP addresses only to computers that are active on a TCP/IP
network, non-active computers do not need to reserve an IP address. This helps workgroups that
have limited numbers of IP addresses. DHCP also simplifies the process of setting up clients. Instead
of having to remember which IP addresses you’ve assigned and which addresses are free, you can
simply configure the client for DHCP and let the DHCP server do the rest (Refer to Chapter 5 - Client
Setup).
To display the DHCP Server Setup dialog box, click the DHCP Server button on the Proxy Setup
menu. To enable the DHCP Server, click (check) the Enable option and make appropriate choices.
Chapter 4 - ProxyServer Software
The DHCP Server Setup menu allows you to customize each client PC configuration from one
central point. The Manage Addresses group allows you to establish the range of IP addresses for
the workgroup (From - To). You can then exclude specific addresses from that range in the Exclude
Range field. Excluded addresses (individual IP addresses or a range of addresses) are computers
with static IP addresses (e.g., a DNS server , a WINS server, and the DHCP server itself). You can
also add, delete, edit, and bind addresses using the corresponding buttons in this group.
The Option Types and Values group at the bottom of the dialog box allows you to customize the
configuration of the client platform. You can add, delete, and edit an option by highlighting it and clicking the appropriate button. You cannot, however, edit or delete entries provided in the default list.
This group includes the Router Address which is the location on the IP subnet that a client can use;
the Domain Name which is the human-readable Internet name of your IP domain; the Reassembly
size which sets a maximum datagram reassembly size; the Default IP TTL which sets the IP time-tolive limit (max. 255); the MTU (Maximum Transmit Unit) which sets the largest possible unit of data
that can be sent; the Default TCP TTL which sets the TCP time-to-live limit; and the Lease time
option which sets the time duration that an IP address is assigned to a client.
When a client requests an IP address, it is given that address for a specific duration of time. Once the
time duration has expired, the client must have received an extension on the lease or received
another IP address to use. The default lease is 65535 seconds (18.2 hours). Assigning lease time
depends on your goals and the site’s usage patterns. For example, if you have more users than IP
addresses, a shorter lease (hours) would be appropriate; however, if students at a university have
their computers turned off for a long period of time (and you want them to keep their IP addresses),
then a longer lease (weeks) would be appropriate.

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. This
list includes many of the most common port usages; however, not all are included because an
increase in the number of port usages supported means a possible decrease in performance speed
and an increased security risk.
Use the Add/Edit Entry dialog box to add or edit ProxyServer applications. For procedural details,
refer to the ProxyServer Help.
The option to add ProxyServer applications is important as new software programs are continually
being developed to perform useful tasks. For example, you may want to add new database
managers, spreadsheets, communications packages, graphics programs, etc., anything that would
make your job easier.
Editing considerations might mean enabling/disabling protocols (both TCP and UDP are enabled by
default), changing the ProxyServer description (to be more easily identified), or changing the range of
port numbers to exclude/include other users (refer to the ProxyServer Help for details).
You must first determine which currently unsupported applications can be proxied. You can refer to
RFC 1700 on the Internet which defines the Internet Protocol suite. RFC 1700 identifies the
parameters, such as Internet address, domain names, autonomous system numbers, protocol
numbers, port numbers, and many others. Once the necessary information has been determined,
you can add the application(s) to the supported list. Without this information, the Proxy will not allow
packets through to the Internet from the unknown software.

MTPSR1-202ST
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.
These filters are based on three basic filter types: Internet Sites (IP Address) (both dotted decimal
and Domain Name), Client Workstation (MAC address or IP address), or Application. To install a
filter, you must first choose one of these basic filter types. Refer to the ProxyServer Help for details
on how to configure the Filter option.
For example, in a filter set up by Domain Name, the system administrator could restrict all users at a
particular site from accessing game sites, X-rated sites, etcetera; or, users at a particular MAC
address or IP address could be restricted from using the services of the ProxyServer; or, you could
restrict all users from accessing specific applications (e.g., FTP, chat, etcetera).
Note: The Filter option does not perform content filtering; rather, the system administrator needs to
restrict users from the particular Internet site, client workstation, or application through the Filters
dialog box.
Note: Adding applications may decrease performance speed and increase security risks. Therefore,
you may want to delete unused or rarely used applications.
To further enhance the security of the firewall network, the FTP button on the Proxy Applications
configuration dialog box allows you to change the FTP Control Port and Data Port Numbers. If you
do change these numbers, make certain that you inform users who need to access the FTP server
what the new numbers are. By default, the FTP server’s Control Port Number is 21 and the Data Port
Number is 20.

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 the 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
204.111.2.60
Secure
LAN
Web Server
204.111.2.30
FTP Server
204.111.2.20
In a normal Internet connection with a router connected to the Internet, you need a static IP address
for each function (server) you want to perform on the Internet. For example, to have a Web server
browse the internet for you, you need an IP address so that the router knows where the traffic is
coming from and where to send the reply . In our normal Internet connection we have assigned an
address of 204.111.2.30 for the Web server, address 204.111.2.20 for the FTP server, and
204.1 11.2.60 for the Firewall.
To reduce the number of static IP addresses, the ProxyServer’s virtual enable feature allows you to
map multiple local servers to a single static IP address or to a Global Dynamic WAN port address.
The virtual server feature enables the ProxyServer to take requests from different servers (functions)
and interact with the Internet based on the functionality of the request. In the normal Internet
connection, this was a physical linkage to a specific IP address. The virtual server feature is a
functional connection. Functionality is defined by how the server is used; i.e., the Web server uses a
www-http protocol, an e-mail server uses pop-3 and SMTP protocol. Therefore, multiple requests
can be sent to the Internet over a single physical connection and the ProxyServer will know which
server is requesting service. The following illustration shows how a ProxyServer is connected to the
Internet with a single static IP address or Global Dynamic WAN port address and the same servers
used in the normal Internet connection are now connected to the Internet through the ProxyServer.
Now, if instead of mapping a static IP address from your ISP to the ProxyServer, you employed MultiTech’s Global Dynamic WAN port addressing method, you no longer have to be concerned with a
single static IP address from your ISP. Y ou can assign a predefined Global Dynamic WAN port
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 the W AN port.

The Virtual Server Setup dialog box defines how the servers are connected to the one global IP
address. The static IP address that we established in our virtual server connection example above is
added to the Global IP Addresses group in the Virtual Server setup dialog box. This could also be a
Global Dynamic WAN address.
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 the activity of the traffic to and from
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,
192.168.1 1.40 to the e-mail server, and 192.168.11.50 to the MultiVOIP.
MTPSR1-202ST
43
ProxyServer User Guide
These local addresses are then mapped to the global address by function. The FTP server was
assigned an IP address of 192.168.11.20 with a TCP and UDP protocol and a port number of 20 and
21. The Mapping Details [Local] group in the Virtual Server Mappings dialog contains the FTP
server local mapping information. When the FTP server mapping information is entered, the Web
server can be mapped to the global address by entering the IP address 192.168.11.30 in the Local IP
Address field of the Mapping Details [Local] group with its protocol and port information. Then the
mail server, and if a MultiVOIP is used in the local network - its mapping information, can be added to
the local mapping group.
The Virtual Server Setup dialog displays all the local mapping information.

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. The service could be anything. Usually it is
terminal emulation. The ProxyServer has a Telnet server that allows multiple clients to connect and
request to use Telnet service, usually terminal emulation. T elnet is most often implemented over TCP.
TFTP is a file transfer protocol that uses UDP and provides a simple method for transferring files
between two nodes (the server and the client).
To display the Applications Setup dialog box, click Others on the Proxy Setup main menu.

Chapter 5 - Client Setup
ProxyServer User Guide
Introduction
The information provided in this chapter enables multiple users to configure their PCs to access the
Internet through a ProxyServer. The procedures are divided into two sections, based on operating
platform. The first section covers configuration of Windows 98/95 PCs, and the second section
covers configuration of Windows NT (4.0 Workstation) PCs.
Before you Begin
Before you begin the client setup process, read through the following requirements:
ProxyServer
The ProxyServer was configured by the administrator who, while installing the software, determined
that the ProxyServer would either automatically assign Internet (IP) addresses, or require that they
be assigned manually to each client PC. Also, the administrator assigned an IP address to the
ProxyServer’s Ethernet port, and assigned user names and passwords to the WAN links. All these
factors play a role in client configuration. Make certain that you are aware of the decisions made prior
to setting up client PCs.
PC
To access the ProxyServer, your PC must have communications capability including hardware such
as a network card and any necessary software.
If the ProxyServer does not automatically assign an IP address to each PC, you will have to obtain it
from your network administrator. You will also need the IP address for the ProxyServer (the Gateway
address), and the IP Address of your organization’s Domain Name Server (DNS). All these items are
needed so your PC can identify the ProxyServer as its gateway and properly set up your network
security.
Checklist
A checklist has been provided towards the end of each procedure (Step 16). This checklist is
included in the setup so that you can record all the pertinent information required for the connection
between your PC and the ProxyServer. Keep this as a reference for future upgrades.

Introduction
Multi-Tech’s Remote Access Server for Microsoft network users enables users to dial-out and fax-out
through your MTPSR1-202ST. Remote Access Solution software uses Multi-Tech’s Communications
Services Interface (MCSI - pronounced “Mik-see”). MCSI is a software redirector which complies
with MCSI/NCSI/NASI defacto standards for software redirection.
The Windows© version of MCSI, called WINMCSI, is supported on Win 3.1x, Windows 98/95, and
Windows NT platforms. Since WINMCSI provides data communications connectivity, it needs to be
installed and operating before your data communications application software is started.
