If the Video Firewall feature is enabled (see Upgrading the firmware), you will need to set up one or more routing settings to control how IP traffic flows in and out of the MCU.
It is important that these settings are configured correctly, or you may be unable to make calls to or from the MCU or access the web interface.
To configure the route settings, go to | . |

If both Ethernet ports are enabled, it is necessary to specify which port is used in certain special circumstances. Make
