im new here so i might get hated on but i have been tring to figure this out for 2 week on and off. my main issue was when i put a br0 apps stop working and truenas couldn't update i take it away reboot works again i looked at global config looks good VM has internet smb didnt pop up when setting it up but was still there if entered manuely. so after all this time it could of been some box i check or it was on by default dont know but when i unchecked this box all worked and is right with the world, it was the DHCP box in the NIC. i must be stupid but i feel like i have to share this so if other noobs like me see this i could say i help someone.
