The UDgateway®-VPN appliance lends itself admirably to two-way satellite systems. When located on a
satellite infrastructure, it sits between the satellite terminal and the local network, and handles all the
VoIP traffic coming from the company's site. When the appliance is located on a terrestrial infrastructure
of a central site, it can be integrated in any network near the Internet access, generally in a De-Militarized
Zone (DMZ). The appliance can be easily configured via a Web interface. A wizard automates the setup
