The UT-6630 creates an encrypted tunnel through IP networks. It features two gigabit ethernet LAN port and a serial port which is used for initial setup and may be used for a PPP link.

The UT-6630 encrypts data between private networks using the public Internet or any other UDP/IP network as the transport.  The UT series products operate in server-client combinations (or using multiple clients and servers in a system). The UT-6630 may be a server unit for other UT-6630s, UT-3302s, or PCs running UT-SOFT client software. The UT-6630 can also be a client device bridging it's local LAN to another UT-6630 or UT-3302 configured as a server. The UT-6630 supports up to 128 simultaneous client UT 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-6630 trusted and untrusted ports are ethernet 10/100/1000BaseT. .The serial port is used  for initial setup or as a PPP port..

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-6630 serial port is normally used only for setup, but may also be configured as a single port PPP dial in or dial out port.  

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.  The UT-6630 models may involve more export requirements.

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.

Using the ET Encrypted Bridges with 801.Q VLANs
Discusses configuring the ET products to handle 801.Q VLAN traffic. The ET supports 801.Q VLAN tagged packets, and allows a VLAN to span multiple IP networks.

Using the ET Encrypted Bridges with IP Multicast.
Discusses applying the ET products to transport VOIP multicast via non-multicast wide area networks. Examples showing IP voice dispatch radios for public service agencies. The ET supports multi-cast IP over normal uni-cast networks and allows a private multi-cast network to span multiple IP networks.
