Configuring Network574. Select OK, and then press to reboot the system immediately.Network Address TranslationIf you choose to place your video conferencing systems in a private LAN, you must use NAT tocommunicate with outside systems. This may include enabling static NAT on your system.Static NATNAT enables communication between devices on your LAN that have private IP addresses anddevices that are accessed through a public IP network. Static NAT ensures that the same publicIP address always maps to a system’s private IP address so that data from the public networkintended for the private system can be routed to the system reliably.If you are using static NAT to associate a public IP address with the private IP address of yoursystem, you must configure your system to work with your static NAT server.NoteStatic NAT feature parameters on the system are described below:Parameter Description Configuration MethodStatic NATSpecifies the static NAT type. Disabled—the system does notuse the NAT feature. Manual—the system uses themanually configured NATpublic address. Auto—the system obtains theNAT public address from theYealink-supplied server.Remote ControlWeb User InterfaceIf H.460 firewall traversal is enabled on the system, the system will automatically ignore the staticNAT settings for H.323 calls. For more information on H.460 firewall traversal, refer to onEnabling H.460 Support for H.323 Calls on page 110.
