DESCRIPTION

The ET-3302 is a compact, industrial temperature rated device (Internet Appliance) that tunnels layer2 Ethernet. The tunnel can be encrypted with AES or non-encrypted. The ET-3302 features two Ethernet LAN ports (4 port switch on trusted interface)and a serial setup port.

The ET-3302 encrypts data between private networks using the public Internet or any other network as the transport. This creates a flat, bridged network, a private network within public or private networks.

The ET-3302 can be a client or server. As a server, the ET-3302 supports up to 8 client devices. As a client, it can be used in conjunction with a ET-6602 server which supports up to 50 remote ET-6602 or ET-3302 clients.

The ET series uses AES 128, 192 or 256 bit encryption. AES is the US Government standard, selected using an open selection process, to replace DES and 3DES encryption.

The ET-3302 network interfaces are Ethernet only. The serial port of the ET-3302 can be used for initial setup of IP address. The ET-3302 has external 12, 24 and 48 volt options.

The ET series operates through firewalls with only one port of your choice opened. It bridges all Ethernet protocols including IPX, IP, NetBEUI, and other proprietary protocols. The ET series is straight-forward, easy to configure and maintain. The ET series has state-of-the-art AES encryption security without the configuration complexity of VPN.

For encryption of serial RS-232 links not involving ethernet or IP, see our SE-6600 product line.

Due to the encryption employed in these products, ET series products are export controlled items and are regulated by the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce. The ET-6602 and ET-3302 are classified as mass market encryption devices and may not be exported or shipped for re-export to restricted countries in Country Group E:1. They are shippable to most other countries.

APPLICATIONS

How it works

The ET family products create an encrypted tunnel which passes Ethernet packets between two trusted LAN segments. All ethernet protocols are bridged between the ET units. The ET only operates in conjunction with other ET units. One unit is required for each location. Multiple client units may be connected to the same host unit, and a client may be connected to multiple host units (daisy-chained operation). A host unit may be configured to block client-unit to client-unit connections, or to allow them. All ET series units are compatible.

All DCB ethenet encryptors operate similarly, with differences being in the protocols, capabilities, and authentication methods. Since the topology is comparable for all of them, we show application notes for all these products together.

UT Product Security In Perspective
This document provides an overview of the UT security perspective as well as best practices for configuring UT encryptors.

Redundancy Techniques Using DCB Tunnel Devices and Software.
Users have come to rely on DCB tunnel products to implement secure networks for mission critical applications in which downtime must be kept to a minimum. Thus it is not unusual for customers to ask questions about techniques that may be applied to make the tunnel network more robust. This document describes some of those techniques with examples.

Quick-start guide to the XT-3306.
This application note guides the new XT-3306 user from opening the boxes to having a working encrypted tunnel between two XT-3306 units on a test bench. Step-by-step instructions make it quick and painless to learn the configuration process. One difference between the XT and the UT/ET families is that the XT allows the selection of TCP and UDP protocols for the tunnel path.

Troubleshooting guide for the above Quick-start.
If it didn't go well and doesn't immediately work, this guide offers some troubleshooting hints. Most people won't need this, but it's here if you do.

Encrypted Bridge Installation Option
An application note describing an appliance-like installation that allows the Tunnel to be located anywhere on the local LAN. Known around DCB as the "Single-Port Installation".

Using the UT Encrypted Bridges and UT-SOFT with IP Multicast.
Discusses applying the UT products to transport VOIP multicast via non-multicast wide area networks. Examples showing IP voice dispatch radios for public service agencies. The UT supports multi-cast IP over normal uni-cast networks and allows a private multi-cast network to span multiple IP networks. The UT-SOFT software client allows any PC to be a securely connected node on a remote network

Motorola MIP 5000 VoIP Radio Console VPN Solution Guide
This Motorola produced MIP 5000 VoIP Radio Console VPN Solution Guide features a virtual private network (VPN) solution that has been tested with MIP 5000 VoIP Radio Console. The VPN solution uses a pair of encrypted Ethernet bridges to provide a secure Ethernet tunnel between the dispatch center and a remote MIP 5000 console. The secure Ethernet tunnel supports a remote console operator receiving audio from and transmitting audio to radio channels and other MIP 5000 consoles using AES encryption.

UT Tunnel Installation Note - "Living On a Wild Feed... Safely"
This short application note summarizes the options and requirements for directly connecting the untrusted interface of UT encrypted tunnels to the Internet. Yes, the UT tunnels may be safely living on the wild side of your firewalls and if properly configured appear to be a "black hole" to your adversaries!

Using the UT for Remote Management Applications Since the UT along with UT-Soft enables a remote workstation to have a virtual presence on a remote LAN segment, it's quite useful for network monitoring and analysis, similar to a RMON without the headaches. Download an application note that discusses using UT-Soft and our UT servers for remote LAN network montoring.

The UT series operates similarly to our ET series encrypted tunnel. The main difference between the two product lines is that the UT uses UDP/IP protocol for the tunnel link while the ET uses TCP/IP for the tunnel link protocol. The following ET application notes apply to the UT as well as the ET series.
