As it stands, I have NPM setup as a custom app in Dragonfish with a static IP from the bridge interface. Accomplishing this was quite easy, needing to configure only these two aspects:
Fast forward: Upgrading to EE broke this as there’s no easy way to set a static IP like before. So, as the title says, I’m looking for a recommendation from those who are a lot more knowledgable than me 
on how to accomplish this. I’ve read thru a few different threads, but nothing is too concise and I’d like the simplest, most no-nonsense approach.
Arguably, this shouldn’t be any more complicated to accomplish than before, and I’d prefer to work entirely within TrueNAS if at all possible.
