1 Introduction

The SINAUT MD740-1 serves the following purpose:

•

GPRS

modem

•

VPN router

•

Firewall

The device establishes secure IP data connections by radio

•

via the GPRS (

eneral

acket

adio

ervice) of a GSM

network (

lobal

ystem for

obile

Communication

= mobile

radio network).

To do so, the device combines the following functions:

•

GPRS modem for flexible data communication via GPRS

•

VPN router for secure data transfer via public networks (IPSec

protocol, 3DES data encryption, AES encryption)

•

Firewall for protection against unauthorised access. The

dynamic packet filter inspects data packets using the source
and destination address (stateful packet inspection) and blocks
unwanted data traffic (anti-spoofing

The device is configured simply using a Web browser.

VPN features

•

Protocol: IPsec (tunnel and transport mode)

•

IPsec DES encryption at 56 Bit

•

IPsec 3DES encryption at 168 Bit

•

IPsec AES encryption at 128, 192 and 256 Bit

•

Packet authentication: MD5, SHA-1

•

Internet Key Exchange (IKE) with Main and Quick Mode

•

Authentication: Pre-Shared Key (PSK), X.509v3 certificates

•

DynDNS

•

NAT-T

•

Dead Peer Detection (DPD)

Firewall features

•

Stateful Packet Inspection

•

Anti-spoofing

•

NAT

Masquerading)

•

Port

Forwarding

Other features

•

DNS
