Firewall User Guide
Introduction
Welcome to Multi-Tech's new Dual Ethernet ProxyServer, model MTPSR1-120, (hereafter, Firewall) a
high speed Internet access device that provides firewall protection to your corporate (secured) LAN
and allows Internet access to the Internet Services Network (public LAN) that resides outside the
firewall. Internet access can be provided through new technologies, such as cable or DSL modems,
connecting to an existing high speed public LAN, or connecting the RS232 WAN port on the back of
the unit that allows Internet access up to T1/E1 access speeds. The Firewall provides two Ethernet
connections that implement firewall protection and gateway security for your LAN resources and
provides megabit data transfer rates (up to 20 times faster than a 56K modem) for your Internet
access.
The Firewall provides two Ethernet 10Base-T ports which connect your private secured LAN (on the
Ethernet 1 jack) to the Internet Services Network resources (public LAN, on the Ethernet 2 jack),
and a Command port for configuration. An additional RS232/V.35 port is provided for an alternate
connection to an external WAN for connecting your secure corporate LAN directly to an ISP.
System management is provided through the command port using bundled Windows® software
which provides easy-to-use configuration menus.

Preview of this Guide
This guide describes the Firewall and tells you how to install and configure the unit. The information
contained in each chapter is as follows:
Chapter 1 - Introduction and Description
Chapter 1 describes the Firewall’s front panel indicators and back panel connectors and switch, and
includes a list of relevant specifications.
Chapter 2 - Installation
Chapter 2 provides information on unpacking and cabling your Firewall. The installation procedure
describes each cable connection.
Cabling considerations involve deciding how you are going to connect your PC to the Firewall to
configure it for proper operation in your system. One option is to connect a PC COM port (1 thru 4)
through the supplied command cable to the COMMAND port on the Firewall. The other option is to
connect your PC’s network interface card (NIC) to a hub on your Private LAN and connect the
ETHERNET 1 jack of the Firewall to your Private LAN and then assign the Firewall an IP address on
your Private LAN. During software installation, the Firewall will detect automatically all Firewalls and
ProxyServers on the LAN and will let you select which one to configure.
Your final cabling consideration involves deciding which back panel connector you will use to connect
your Private (secured) LAN to the Internet. Your options include the ETHERNET 2 LAN jack or the
RS233/V.35 WAN connector; only one Ethernet connection method can be used.
