Introduction
Welcome to Multi-Tech's new DSU ProxyServer, model
number MTPSR2-201, a single, secure gateway that provides
multiple LAN users with high performance Internet access
over a leased line. The DSU ProxyServer functions as a TCP/
IP proxy server that resides on the outer edge of your firewall
and provides up to 56K of bandwidth to LAN users. The DSU
ProxyServer features a 10BaseT port for local LAN
connection, a command port for configuration, a 56K bps DDS
4-wire WAN connection, and a RS232 port for auto-dial
backup in case the leased line connection is lost. System
management is provided through the command port using
bundled Windows® software which provides easy-to-use
configuration menus.
The MTPSR2-201 also supports dial-in Remote Access Server
(RAS) when the WAN 2 port is configured to support it. Refer
to the Software Installation section of this guide, and to your
ProxyServer User Guide for more details on RAS.
