  1. 1. Configuring the Avaya™ VSU100R Gateway, Netscreen 208 and 204 VPN Gateways, Avaya™ IP Telephones and Softphones in a VPN Environment – Issue 1.0 Abstract These Application Notes describe the setup and configuration of devices in the following VPN environments: Netscreen 208 VPN Gateway and Netscreen 204 Gateway, Netscreen 208 and Avaya™ VSU100R Gateway.

  2. 2. 1. Introduction These Application Notes describe the setup and configuration of devices in the following VPN environments: Netscreen 208 VPN Gateway and Netscreen 204 VPN Gateway, Netscreen 208 VPN Gateway and Avaya™ VSU100R Gateway. A detailed illustration of the configurations tested along with a list of test equipment is contained herein. Figure 1 represents the sample network topology. In one configuration a site-to-site tunnel was established between the Netscreen 208 and Avaya VSU100R for secure voice and data transmissions. A second configuration replaced the VSU 100R with the Netscreen 204. The Lucent AP 1000 was included in the test to accommodate the router functionality. A network sniffer was used to verify that the packets going through the tunnels were encrypted.
