5 Chapter 1 Installing NAT Proxy Server 5 Chapter 1 Installing NAT Proxy Server Because of the lack of real IP addresses, many Internet facilities including Blaze or Savanna Series IP PBX Communication Systems must be installed behind NAT or firewall. When IP PBX system travels through virtual or floating IP, sometimes the voice packets cannot traverse NAT or firewall successfully and cause the problem of one-way or failed phone communication. This chapter guides you through the preparation, installation and basic configuration of DSG NAT Proxy.

6 6 Chapter 1 Installing NAT Proxy Server Before You Start DSG NAT Proxy is an electronic product. Please follow the recommendations below when you install or operate your system in order to avoid any injury and damage. Safety Recommendations Always use ESD-preventive tools when you plug the power cord. Do not disassemble or remove chassis cover of the system. If there is any problem of your system, please contact our service representatives. Environmental Prerequisites DSG NAT Proxy needs to be installed in clean, dry, adequately ventilated areas. The system can be placed in a control room or on a rack. Please remain the control room in a suitable temperature and adequately ventilated environment.

For more details, please refer to InterPBX Administration Installation and Configuration Guide: Multi-Server Management>Server Information Server IP: Input the REAL IP address of the NAT router where the InterServer is located. If a dynamic Internet connection is adopted, such as PPPoE, and a fixed IP address for WAN connection is not applicable, you may skip this item. Instead, please input the MAC address of the InterServer as described below. MAC: If a dynamic IP is applicable for InterServer s WAN connection, input the InterServer s MAC address. As long as listed on the InterServer Page, the InterServer and its associated off-premises extensions and voice gateways will not need to open specific service ports when they are deployed behind NAT.
