You can download Feed the Beast and ATLauncher server mod packs by going into the FTB or ATLauncher client on your desktop and searching for the mod pack, then clicking 'Create Server' or 'Download Server'. First you'll need the mod pack server files that you want to use.You will need to use a desktop FTP client to connect to your servers FTP and upload the files. This is a brief guide, and we can always setup a mod pack for you manually if you submit a ticket in your client area. This will show you how to setup a mod pack on your Minecraft server. Tl dr: I need guidance setting up a Revolution|3 Minecraft server from the ATLauncher (preferably through a MineOS jail) on FreeNAS 11.3-U1.View our YouTube guide on how to setup a mod pack manually on your server, alternatively, scroll down to see our automatic setup which is available for some systems. None of this is particularly intuitive for me, but given that I've been able to do it before, I'm sure its possible. I get different vnet errors and one time I got MineOS jail sort of working, but none of UI was loaded correctly and wouldn't respond to any input. I have read through the guides that I used before, as well as new ones I could find, but I still can't get it working.

I tried just going back to FreeNAS 11.0-U4, but since the repositories aren't available, I can't install things in the jails. The problem I'm having is that since the original server was built, FreeNAS has changed its UI and jails have been changed to iocage, making my original documentation hard to use or outright impossible. About two weeks ago, I rebuilt the system using new hardware and installed FreeNAS 11.3-U1 onto it with the intent to revive the Minecraft server. I got some help here regarding setting it up and it ran fine for a while before some unrelated problems happened and I had to scrap it. So about two and a half years ago, I built a FreeNAS 11.0-U4 system to run a Revolution|3 modded Minecraft server among other things.
