Network > Global Configuration has all the general TrueNAS networking settings that are not specific to any interface.

Disruptive Change

Making changes to the network interface the web interface uses can result in losing connection to TrueNAS! Fixing any misconfigured network settings might require command line knowledge or physical access to the TrueNAS system.

Global Configuration Settings

Options are organized into several categories.

Many of these Interface, DNS, and Gateway options are also configured in the Console Setup Menu. Be sure to check both locations when troubleshooting network connectivity issues.

Hostname and Domain

Many of these fields have default values, but can be changed to meet requirements of the local network. The Hostname and Domain display in the Dashboard > System Information card. Some options only display when the appropriate hardware is present.
