Unable to access your TrueNAS host from a VM? Host unreachable? Then you need a Bridge Network!
In this video tutorial I explain TrueNAS Bridge Networking, how to configure a Static IP and make a Network Bridge without losing connectivity, and how to set bridge networking on your VMs and Sandboxes/Jails in order to correct Host/VM network issues.
And finally I performance test the bridge network
Saw your posters in the background. May the 4th be with you!
Set up your main interface with static IP by disabling DHCP and adding IP alias (use the same IP you are connected to for easy results)
Test Changes and then Save them (important)
Edit your main interface, remove the alias IP
Don't click Test Changes
Add a bridge, name it something like br0, select your main interface as a member and add the IP alias that you had on main interface
Click Apply and then Test Changes
after applying all this is faults back and ip is not assigned to br0
Did you shutdown any jails, virtual machines and your apps pool?
Yes, I was trying to configure bridge on a fresh install without apps and vm installed.
Truenas was installed on bare metal, now I installed it as vm on proxmox with hardware pass through and was able to configure bridge.
Hi mate, this guide is perfect, up to when removing the static IP from the ethernet interface to add the bridge, I receive the error “[TRUENAS IP]’ is being consumed by Applications, please use a different node IP in applications configuration.”
I’ve tried disabling all my apps, all VM’s and any services like NFS, still receive that error. (Haven’t done anything with jails).
Any tips what it could be? Even restarted 
Yes, I neglected to cover the Apps.
Go to Apps, then Settings → Unset pool (this will disable apps)
Make / Test / Save the changes (ie add the bridge etc)
Then go back to Apps and reselect your pool.
Your apps should re-deploy with your data intact.
I tested this with NextCloud configured with ix-volumes for data.
Works a treat thank you very much. I see you’ve answered that in the comments as well now. May want to add to video description or pin that/their comment?
Do you know how can I do this for an app?
I’m trying to setup music-assistant and everything looks correct but I get no sound from the speakers.
Probably because it’s still using the default k3s interface instead of the external one. Any thoughts? Thank you!
Mrkhachaturov, Did you ever get this working. I’m in the same boat. I’ve followed the instructions by Stux and others, including removing the apps pool, shutting down VMs, system services, etc. The bridge never sticks after the test and all network settings revert. How did you get it to work?
@Stux great guide. Thanks for knowledge. I was easily able to set the bridge up following your guidance; however, I’m now in the process of reconfiguring my system and for the life of me I cannot figure out how to actually remove the bridge. Any pointers?
Do it backwards 
I had assumed that, and that’s how I had begun. I must have fubarred something along the way, however. I finally got the bridge removed through trial and error.
Sorry, didn’t have a lot of time to tap out a response previously.
The trick is to treat it much the same as creating the bridge in the first place, but to do it in reverse. You still need to shut down VMs etc.
Then you remove the IP from the bridge (without saving), delete the bridge (without saving), and add the IP to the base interface, then save.
I have tested that many many many times as part of testing the forward process
