• How does UPnP work?UPnP networking technology provides automatic IP configuration and dynamic discovery of devices addedto a network. Services and capabilities offered by networked devices, such as printing and file sharing, areavailable among each other without the need for cumbersome network configuration. In the case ofKX-NTV150/KX-NTV160, you will see KX-NTV150/KX-NTV160 shortcuts under My Network Places.• Enabling UPnP port forwarding allows the KX-NTV150/KX-NTV160 to open a secondary HTTP port on therouter-not HTTP port-meaning that you have to add the secondary HTTP port number to theKX-NTV150/KX-NTV160 public address in order to access the KX-NTV150/KX-NTV160 from the Internet.For example, when the HTTP port is set to 80 and the secondary HTTP port is set to 8080, refer to the listbelow for the IP address of the KX-NTV150/KX-NTV160.From the Internet In LANhttp://203.67.124.123:8080 http://192.168.4.160 or http://192.168.4.160:8080• If the PPPoE settings are incorrectly configured or the Internet access is not working, restore theKX-NTV150/KX-NTV160 to factory default; please refer to Restore on page 54 for details. After theKX-NTV150/KX-NTV160 is reset to factory default, it will be accessible on the LAN.PortHTTPS port: By default, the HTTPS port is set to 443. It can also be assigned to another port number between1025 and 65535.FTP port: The FTP server allows the user to save recorded video clips. You can utilize Panasonic's InstallationWizard to upgrade the firmware via FTP server. By default, the FTP port is set to 21. It also can be assignedto another port number between 1025 and 65535.Two way audio port: By default, the two way audio port is set to 5060. Also, it can also be assigned to anotherport number between 1025 and 65535. Note that as JPEG only transmits a series of JPEG images to the client,to enable the two-way audio function, make sure the video mode is set to "H.264" on the Media ® Video ®Stream settings page and the media option is set to "Media ® Video ® Stream settings" on the Clientsettings page.82 User’s Manual2 Software
