Add/Edit Interface Configuration Screens Interface Settings Bridge Settings Link Aggregation Settings VLAN Settings Other Settings Aliases The Interfaces widget on the Network screen displays interface port names and IP addresses configured on your TrueNAS system, as well as their upload/download rates.
Use Add to open the Add Interface configuration screen.
Click on an interface to open the Edit Interface configuration screen.
Click the edit icon next to an interface to open the Edit Interface configuration screen.
Use the Global Configuration Settings screen to add general network settings like the default gateway, DNS name servers to allow external communication.
To add new or change existing network interfaces see Managing Interfaces.
Disruptive Change
You can lose your TrueNAS connection if you change the network interface that the web interface uses!
You might need command line knowledge or physical access to the TrueNAS system to fix misconfigured network settings.
One Static IP Address or Multiple Aliases? Adding an Interface Editing an Interface Deleting an Interface Adding Alias IP Addresses You can add new or edit existing network interfaces on the Network screen.
Why should I use different interface types? expand LAGG (Link Aggregation)
You should use LAGG if you want to optimize multi-user performance, balance network traffic, or have network failover protection.
For example, Failover LAGG prevents a network outage by dynamically reassigning traffic to another interface when one physical link (a cable or NIC) fails.

The Global Configuration widget displays the general TrueNAS networking settings not specific to any interface.
The SCALE information dislplayed the Global Configuration widget is the equivalent of the information displayed on the TrueNAS CORE Network Summary screen. Global Configuration settings configuration screens are similar in both SCALE and CORE but SCALE includes external communication settings. Use Settings to display the Global Configuration screen where you can add or change global network settings.
Setting Up External Communication for Services Setting Up Netwait Use the Global Configuration Settings screen to manage existing general network settings like the default gateway, DNS servers, set DHCP to assign the IP address or to set a static IP address, add IP address aliases, and set up services to allow external communication.

In general, a bridge refers to various methods of combining (aggregating) multiple network connections into a single aggregate network. TrueNAS uses bridge(4) as the kernel bridge driver. Bridge(8) is a command for configuring the kernal bridge in Linux. While the examples focus on the deprecated brctl(8) from the bridge-utilities package, we use ip(8) and bridge(8) from iproute2 instead. Refer to the FAQ section that covers bridging topics more generally.
To set up a bridge interface, from the Network screen:
Console Setup Menu Network Settings Configuring Required Network Settings Changing the Administrator Password Resetting the System Configuration Completing your System Setup The Console setup menu (CSM) displays at the end of the iso installation process and after the system boots up. You can access this menu to administer the TrueNAS system if it has a keyboard and monitor.
By default, TrueNAS does not display the Console setup menu when you connect via SSH or the web shell.
TrueNAS Enterprise The instructions in the article only apply to SCALE Enterprise (HA) systems. SCALE Enterprise (HA) systems use three static IP addresses for access to the UI:
VIP to provide UI access regardless of which controller is active. If your system fails over from controller 1 to 2, then fails over back to controller 1 later you might not know which controller is active. IP for controller 1. If enabled on your network, DHCP assigns only the Controller 1 IP address.
In general, a link aggregation (LAGG) is a method of combining (aggregating) multiple network connections in parallel to provide additional bandwidth or redundancy for critical networking situations. TrueNAS uses lagg(4) to manage LAGGs.
To set up a LAGG, from the Network screen:
Click Add in the Interfaces widget. The Add Interface configuration screen displays.
Select Link Aggregation from the Type dropdown list. You cannot change the Type field value after you click Apply.
A virtual LAN (VLAN) is a partitioned and isolated domain in a computer network at the data link layer (OSI layer 2). Click here for more information on VLANs. TrueNAS uses vlan(4) to manage VLANs.
Before you begin, make sure you have an Ethernet card connected to a switch port and already configured for your VLAN. Also that you have preconfigured the VLAN tag in the switched network.
To set up a VLAN interface, from the Network screen:
