DESCRIPTION

The UT-6602 encrypts data between private networks using the public Internet or any other UDP/IP network as the transport. The UT-6602 also supports cellular broadband modems via the 10BaseT interface. The UT series products operate in server-client pairs (or using multiple clients and servers in a system). The UT-6602 can be a server unit for other UT-6602s, UT-3302s, or PCs running UT-SOFT client software. The UT-6602 can also be a client device bridging it's local LAN to another UT-6602 or UT-3302 configured as a server. The UT-6602 supports up to 50 client UT locations, the UT-3302 supports 8 client UT units. Other models support 100 or more remote UT client locations.

The UT series uses AES encryption. AES is the US Government standard, selected using an open selection process, to replace DES and 3DES encryption.

The UT-6602 trusted port is ethernet 10/100BaseT. The WAN, or untrusted, data port is an ethernet port. WAN port data can be sent encrypted or unencrypted. The serial port is used only for setup.

The UT series operates through firewalls with only one UDP port of your choice opened. It bridges all ethernet protocols including IPX, IP, NetBEUI, VOIP, and other proprietary protocols as well as multi-cast. The UT series is straight-forward, easy to configure and maintain. The UT series has state-of-the-art AES encryption security without the configuration complexity of typical VPN equipment. One UT encrypts a location for 100s of PCs and other devices.

The server typically has a fixed IP address. Clients may have fixed IP addresses or obtain a dynamic address. Dynamic DNS is also supported for server locations that do not have a fixed address available.

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

The UT-6602 serial port may also be configured as a single port UDP terminal server. This allows the UT-6602 to interoperate with DCB's EtherPoll SCADA communications system.

Due to the encryption employed in these products, UT 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 UT-6602 and UT-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.

Quick-start guide to the XT family products.

This application note guides the new XT user from opening the boxes to having a working encrypted tunnel between two XT units on a test bench. Step-by-step instructions make it quick and painless to learn the configuration process. Uses the XT-hEX as an example, but also covers other XT products.

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.

What Do Those Tunnel Log Entries Mean?

When analyzing logs from DCB Tunnels (XT, UT, ET, and FT), there are often log entries that are surprising to the new user. We discuss those here.

Configuring the LAN3 on the XT-hEX, a Quick-start guide.

Most people won't need this, but if you want to use the third LAN port on the XT-hEX, this information will help you configure it.

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.

DCB's Encryption Product Export Statement

Some of our encryption products are export controlled items and are regulated by the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce. Some 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 exportable to most other countries. Read our Encryption Product Export Statement here for more specifics.

Using XT Tunnels with IP Radio Dispatch Systems.

Radio installers rely on DCB tunnel products to implement secure networks for mission critical applications. DCB Encryptors (XT, UT, and ET roducts) enable IP dispatching across multiple networks. They remove the multi-cast problem faced in many IP network installations so are frequently used along with Telex, Motorola, Kenwood, Harris, Zetron, AVTEC, and other two-way radio consoles. This document describes some of those techniques with examples we've seen at PSAPs and other dispatch centers.

Tunnel Product Security In Perspective.

Our encrypted tunnel appliances provides a LAN -to- LAN encrypted tunnel between locations. It employs a layer three (UDP/IP or TCP/IP) connection between two or more tunnel devices to create a secure, AES encrypted tunnel. For export purposes, the Some models are considered a Mass Market Encryption Device by the Department of State Bureau of Industrial Security and are export limited.

This product line meets HIPPA and most government standards for non-classified data transfer. However, it is not NIST FIPS 140-2 approved. For a FIPS 140 approved product, the (more expensive) FT line of encryption appliances is required. This note discusses the security implications of using our encrypted tunnels.

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.

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.
