Working through setting up firewall rules to only allow what’s needed on the external side and was wondering if TrueNAS posts a list of what IPs are needed to allow basic functionality? At the moment, this is a basic install. No plugins. Been working through them and stuck on what the following act…

By whitelisting specific IP:s I suspect you are creating a lot of future maintenance work…

I think OP is doing that. The question is, “what external IP addresses does TrueNAS need to be able to reach in order to function properly?” And the answer, AFAIK, is none, other than whatever NTP server you’re using. That means, of course, that there are some things that won’t work: You won’t …

Well that’s unfortunate. This really needs to be marked on their downloads page and software comparison page. Chart still shows CORE being a viable option. This install is new and just finished pulling 13TB down to get rid of my cloud storage. Guess I’ll take a look at the migration steps in the do…
