Y’all, this is gonna be super broad, and I apologize for that, but I’m pretty new to all this and am looking for advice and guidance because I’m pretty overwhelmed at the moment. Any help is very, very appreciated.
For the last ~3 years, I’ve been running a basic home server on an old computer. Right now, it is hosting HomeAssistant, Frigate NVR, their various dependencies, and other things I use (such as zigbee2mqtt, zwave-js-ui, node-red, mosquitto, vscode, etc).
This old server has been my “learning playground” for the last few years, as it was my very first home server and my first foray into linux. That said, it’s obviously got some shortcomings in terms of basic setup (it’s probably not secure, it’s definitely messy, some things don’t work as I’d like, etc). It’s currently on its way out (the motherboard is slowly kicking the bucket on me), so it’s time to replace it, and I kind of what to start over (not completely - I’ve hundreds of automations in home assistant and node-red, for instance, that I don’t want to have to completely re-write, so I intend to export/import those as needed) and do it “right” this time - at this point, I think this is where I’m hung up, paralyzed by a fear of doing it “wrong” and winding up with an inefficient, insecure mess.
The new server, I want to be much more robust in terms of capability, and I have a handful of things I’d really love to do: pi-hole (though I need to buy a new router for this, so that has to come later on unless it’d save a bunch of headache doing it from the get-go), NAS, media server (plex/jellyfin), *arr stuff, as well as plenty of new things I’d love to self-host like Trilium notes, Tandoor or Mealie, Grocy, backups of local PCs/phones/etc (nextcloud?)… obviously this part is impossible to completely cover, but I suspect the hardware (list below) should be capable?
I would love to put all my security cameras on their own subnet or vlan or something to keep them more secure.
I need everything to be fully but securely accessible from outside the network. I’ve recently set up nginx for this on my current server and it works well, though I probably didn’t do it 100% “right.” Is something like Tailscale something I should look to use in conjuction with that? In place of? Not at all?
I’ve also looked at something like Authelia for SSO, which would probably be convenient but also probably isn’t entirely necessary.
Currently considering Proxmox, but then again, TrueNAS would be helpful for the storage aspect of all this. Can/should you run TrueNAS inside Proxmox? Should I be looking elsewhere entirely?
Here’s the hardware for the recently-retired gaming PC I’ll be using:

Also various SSDs and HDDs.
I’m in this weird place where I don’t have too much room to play around because I want to get all my home automation and security stuff back up as quickly as possible, but I don’t want to screw this all up.
Again, any help/advice/input at all is super, super appreciated.
Not sure why you need a new router for PiHole. If your machines all point to the Pihole for DNS, it works. Router has almost nothing to do with what provides DNS, other than maybe having it’s DHCP config include the Pihole for DNS.
Even then, you can setup the Pihole to be both DHCP and DNS (which helps for local name resolution anyway), and then just turn off DHCP in your router.
As I understand it, Tailscale and Nginx fulfill the same requirements. I lean toward TS myself, I like how administration works, and how it’s a virtual network instead of an in-bound VPN. This means devices just see each other on this network, regardless of the physical network to which they’re connected. This makes it easy to use the same local-network tools you normally use. For example, you can use just one sync tool, rather than one inside the LAN, and one that can span the internet. You can map shares right across a virtual network as if it were a LAN. TS also enables you to access devices that can’t run TS, such as printers, routers, access points, etc, by enabling its Subnet Router.
Tailscale also has a couple features (Funnel and Share) which enable you to (respectively), provide internet access to specific resources for anyone, or enable foreign Tailscale networks to access specific resources.
I see Proxmox and TrueNAS as essentially the same kind of thing - they’re both Hypervisors (virtualizatiin hosts) with True adding NAS capability. So I can’t think of a use-case for running one on the other (TrueNAS has some docs around virtualizing it, I assume the use-case is for a test lab, I wouldn’t think running TN, or any NAS, virtualized is an optimal choice, but hey, what do I know? ).
While I haven’t explored both deeply, I lean toward TrueNAS, but that’s because I need a NAS solution and a hypervisor, and I’ve seen similar solutions spec’d many times for businesses - I’ve seen it work well. Plus TrueNAS as a company seems to know what they’re doing, they have a strong commercial arm with an array of hardware options. This tells me they are very invested in making True work well, and they do a lot of testing to ensure it works, at least on their hardware. Having multiple hardware products requires both an extensive test group and support organization.
Proxmox seems equivalent, except they do just the software part, as far as I’ve seen.
Two similar products for different, but similar/overlapping use-cases.
Best advice I have is to make a list of Functional Requirements, abstract/high-level needs, such as “need external access to network for management”. Don’t think about specific solutions, just make the list of requirements. Then map those Functional requirements to System requirements. This is often a one-to-many mapping, as it often takes multiple System requirements to address a single functional requirement.
For example, that “external access” requirement could map out to a VPN system requirement, but also to an access control requirement like SSO, and then also to user management definitions.
You don’t have to be that detailed, but it’s good to at least have the Functional-to-System mapping so you always know why you did something.
You make a very good argument for Tailscale, and I think I’ll definitely be looking deeper into that.
I like your suggestion to map out functional requirements, and then go from there. I think I’ll go ahead and start working on a decent map for that.
As far as the new router for pi-hole… my super-great, wonderful, most awesome ISP (I hope the sarcasm is evident, haha; the provider is AT&T) dictates that I use their specific modem/router (not optional), and they also do not allow me to change DHCP on that mandated hardware. So my best option, so far as I’ve seen, is to use the ISP’s box in pass-through with a better router behind it that I can actually set up to use pi-hole.
Thank you for your thoughts and suggestions! I’m going to take a deeper look at Tailscale and get started properly mapping high-level needs/wants out, with options for each.
Ya don’t need ATT’s modem. Some copy pasta I’ve put together:
If it’s fiber, you don’t need the modem. You’ll still need it once every few months.
Things you’ll need:
Setup: Connect gpon (the little fiber converter box they installed on the wall near modem) wan to any port on 4port switch. Then from switch to gpon port of modem (usually red or green port). Make sure modem fully syncs. Once this happens, you can move the cable from the modem to your own routers wan port. Done! Allow router a few moments to sync as well.
Now, every once in a while they’ll send a line refresh signal that will break this, or if a power outage occurs. In such case, you’ll just plug back in their modem, move cable back to gpon port of modem, wait for sync. Move cable back to router.
Bonus: Hook up all this to a battery backup and you’ll have Internet even during power outages, at least for a while.
Since their modem is handing out DHCP addresses, is there any reason why you couldn’t just connect that cable to your router’s internet port, and configure it for DHCP on that interface? Then the provider would always see their modem, and you’d still have functional routing that you control.
Since consumer routers have a dedicated interface for this, you don’t have to make routing tables to tell it which way to the internet, it already knows it’s all out that interface.
Just make sure your router uses a different private address range for your network than the one handed out by the modem.
So your router should get a DHCP and DNS settings from the modem, and will know it’s the first hop to the internet.
I do this to create test networks at home (my cable modem has multiple ethernet ports), using cheap consumer wifi routers. By using the internet port to connect, I can do some minimal isolation just by using different address ranges, not configuring DNS on those boxes, and disabling DNS on my router.
Their modem is my router; it’s both. That’s why I need a new one, to do exactly as you’re describing (is my understanding, although another post here suggests otherwise).
You should still be able to run your own router with it treating their router as the next hop.
Huh, this is interesting, I’ll have to take another look into this. Thanks for the lead!
And I do have a UPS, and it is, indeed, pretty glorious that my internet, security cameras, and server all stay online for a good bit of time after an outage, and don’t even flinch when the power is only out briefly. Convenience and peace of mind. Well worth a UPS.
Lol, sarcasm received, loud n clear!
Yea, they all suck that way. I still use my own router for wifi. It’s just routing, and your own router will know which way to the internet, unless there’s something I don’t understand about your internet connection. See my other comment below.
Yea, requirements mapping like this is standard stuff in the business world, usually handled by people like Technical Business/Systems Analysts. Typically they start with Business/Functional Requirements, hammered out in conversations with the organization that needs those functions. Those are mapped into System Requirements. This is the stage where you can start looking at solutions, vendor systems, etc, for systems that meet those requirements.
System Requirements get mapped into Technical Requirements - these are very specific: cpu, memory, networking, access control, monitor size, every nitpicky detail you can imagine, including every firewall rule, IP address, interface config. The System and Technical docs tend to be 100+/several hundred lines in excel respectively, as the Tech Requirements turn into your change management submissions. They’re the actual changes required to make a system functional.
