Dual Ethernet ProxyServer User Guide
Introduction
Welcome to Multi-Tech's new Dual Ethernet ProxyServer, model number MTPSR1-120, 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 Dual Ethernet
ProxyServer 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 Dual Ethernet ProxyServer provides two Ethernet 10Base-T ports which connect your
private secured LAN to the LAN 1 connection and the Internet Services Network resources to the
LAN 2 connection, 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.
