Setting Up a Network Bridge

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:

1. Click Add in the Interfaces widget. The Add Interface configuration screen displays.

   

2. Select Bridge from the Type dropdown list. You cannot change the Type field value after you click Apply.

3. Enter a name for the interface using the format bridgex where x is a number representing a non-parent interface. You cannot change the Name of the interface after you click Apply.

4. (Optional but recommended) Enter any notes or reminders about this particular bridge in the Description field.

5. Select the interfaces on the Bridge Members dropdown list.

6. (Optional) Click Add to enter another IP address if desired for this bridge interface. Click Add to display an IP address field for each IP address you want to add.

7. Click Apply when finished.
