Interface Editing

Be careful when configuring the network interface that controls the TrueNAS® web interface or you may lose web connectivity.

Network > Interfaces lists all the physical Network Interface Controllers (NICs) connected to your TrueNAS® system.


To edit an interface, click > next to it to expand the view and provide a general description about the chosen interface, then click EDIT.

If you are a TrueNAS Enterprise customer, remember that you cannot edit an interface if High Availability (HA) is enabled.
Go to System > Failover and check the Disable Failover box, then click SAVE.


Interface editing options are dependent on the Type of interface that you are modifying.

See Interfaces Screen for more information on settings.

Saving Changes

After you’re done editing, click SAVE. You have the option to TEST CHANGES or REVERT CHANGES. The default time for testing any changes is 60 seconds, but you can change it to your desired setting.


After clicking TEST CHANGES, confirm your choice and click TEST CHANGES again.


Users can either SAVE CHANGES or REVERT CHANGES. A user has the time they specified to make their choice. If you select SAVE CHANGES, a dialog box asks you to CANCEL or SAVE network interface changes. Click SAVE.



The system displays a dialog box to show that network interface changes are made permanent.
