Networks

During deployment, these network settings were configured for the appliance: IP address, subnet, gateway, primary DNS, hosts file, and open ports.

The IP address and subnet enable communication between the appliance and other machines on your network.
The gateway enables communication between the appliance and machines on different subnets.
Appliance DNS settings are required for the following:
To connect the appliance to the Internet.
To add assets using only their hostnames (rather than by fully qualified domain names).
To add backup copy cloud targets to the appliance.
To update your appliance from the UI.
To access the Unitrends Community forums from the UI.
The hosts file enables communication between the appliance and its protected assets without using DNS. (But DNS is required for other features and must be set up on the appliance.) During deployment, the hosts file is created and contains an entry for the appliance itself. Additional entries are automatically added to this file any time you add an asset to the appliance or configure a secure tunnel connection (for backup copy to the Unitrends Cloud or to another Unitrends appliance). In most cases it is not necessary to modify this file.
Port security controls which ports are open on the appliance. By default, the appliance is configured with all ports open (port security is set to None Open All). Other port security levels are available and you can close ports by applying one of these other levels.

You can modify the network settings described above as needed. See the following for details:
