MTPSR1-202ST

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.

System management is provided through the command port using bundled Windows

®

 software which

provides easy-to-use configuration menus.
