How To Setup a Network Bridge in TrueNAS (and Why You Should)

Network bridges in TrueNAS allow containers and VMs to have their own IP addresses on the network by attaching multiple MAC addresses to a single physical interface. The setup involves removing the IP from the physical interface, creating a bridge interface with that IP, and adding the physical interface as a bridge member. Multiple bridges can be created for different VLANs, and containers can be assigned to specific bridges during creation. This approach simplifies network card replacement since all containers remain attached to the bridge rather than individual interfaces.
