IPv6 is the next generation Internet protocol replacing the current IPv4 protocol. IPv4 is running out of numbers due to the ever increasing number devices world wide wanting to connect. The rise of the Internet of Things (IoT), where smart sensors in homes, motor vehicles, and businesses all want or need to connect to the Internet to allow data collection and sharing for analytics, device maintenance and monitoring, increased safety and productivity, and overall improvement in consumer and customer experiences is a source of an ever-increasing demand for IP addresses. Because of the length and configuration of IPv6 addresses, there is little risk of this protocol running out of numbers any time soon.

The Console Setup menu 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 with SSH or web shell connections. The admin user, the root user (if enabled), or another user with administrator or root-level permissions can start the Console Setup menu by entering this command:

The instructions in the article only apply to TrueNAS Enterprise (HA) systems.

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 configured for your VLAN. Ensure that you have also preconfigured the VLAN tag in the switched network. Consult with your IT department to obtain this VLAN tag if you are not the network administrator for your systems.

The Network Configuration widget shows the general networking settings for the TrueNAS system.

DNS Servers shows the IP addresses for the primary and secondary name servers.

Default Route shows the IP address for the default gateway.

The remaining general network settings shown in the widget are the system host name, domain name, HTTP proxy address, any configured service announcement, additional domains, the host name database, and the outbound network setting.

The Interfaces widget on the Network screen shows the configured interface port names and IP addresses, and the MAC addresses associated with network interface cards in your TrueNAS system.

Add opens the Add Interface screen.

The more_vert at the right of each interface shows a dropdown list with two options:

• edit Edit - Opens the Edit Interface screen.
• refresh Reset Configuration - Opens the Reset Configuration dialog.

TrueNAS Enterprise

High Availability (HA) Enterprise systems cannot reset or edit interface settings with failover enabled. On systems with HA failover enabled, the refresh Reset Configuration or edit Edit options are disabled. Go to System > Failover to disable failover before attempting to modify interfaces on HA systems.

Follow these best practices for a stable and performant network.

By default, TrueNAS configures the primary network interface for Dynamic Host Configuration Protocol (DHCP) IP address management. Consider assigning a static IP address for increased network stability and communication between devices.

Static routes define specific paths for network traffic that bypass the default gateway.

The IPMI widget on the Network screen shows the available IPMI channels.

Click to open the IPMI manager in a new browser tab where users can log into the IPMI web interface.

Click edit to go to the IPMI configuration screen.

The Static Routes widget on the Network screen shows static IP addresses configured as static routes. Allows manual entry of IP address routes to network destinations outside the TrueNAS network so the router can send packets to a destination network.

TrueNAS does not have defined static routes by default.

Add opens the Add Static Route screen where you can enter a static route to reach portions of the network.
