HA is pretty much the point - and I can’t see any enterprise running without it. Maybe small, but nothing mid or large size. A sector Proxmox can get into at least in small scale (seeing this now actually), and grow.

I wouldn’t be able to function with that level of risk

Multiple clusters. You dont necessarily want all your nodes on a single cluster, and in the enterprise you often don’t.

Your friend is wonderful, I’m so glad you shared

Edit: to be clear this is not sarcasm at all

Looks like a few folks have

Going to have to try this out myself!

Ooh, thats a nice solution! Ive got an old iPad myself that doesnt do much, I could use that and set it up for the kitchen for my wife and I (mealie recipes)

KDE.

I won’t use gnome (I’ve mentioned elsewhere), and unsurprisingly I just dont like it either. The design choices are restrictive, the environment is oversimplified - its just not for me.

Ive used lots of DEs over the years, even fvwm95 (the original, its neat that some folks have updated it though), and at this point if its a desktop its getting KDE.

Off lease lenovo/HP/dell tiny/mini/micro. Keep the NAS for the storage, use the tiny/mini/micro as the media server. Anything with a 6th gen Intel and up will be decent on transcoding (use the igpu), 8th gen and up is better.

Personally I’d put proxmox on it, and run each service as an LXC, or for the little ones, one LXC for docker and throw the docker containers on there.

I have 7 tiny/mini/micros. 3 dell micro, 3 lenovo tiny, 1 HP mini (used to have 2 but one got replaced by a dell).

Powerhouses with low power draw. Highly recommended.

If you do build, I’d say an Intel arc GPU. The rest is just buying stuff that works well with Linux, which is most everything in terms of the basics.

Tape is still the best long term storage medium though.

… I still have probably 100 blank DVDs and a hundred blank CDs.

But I also have a 3.5" floppy drive so I’m not a good measure to go by on these things.

Was that the file transfer allowed for remote code execution one? That’d be the one that sticks out to me. 3 or 4 years ago iirc?

Edit: CVE-2021-27649 is the one that came to mind, not sure if that’s the one you’re referring to.

You were responding to me, and I most definitely didn’t equate the two. Maybe you meant to respond to someone else.

In any case, you can route between vlans (and subnets), but without a route you aren’t communicating between those vlans or.between subnets.

Also, you can have multiple subnets in a vlan, but you can’t have a single subnet across vlans.

The range (x.x.10.x and x.x.20.x from your example) is only the subnet side, you could have both of those subnets in one vlan. But you could not, for example, have x.x.10.x/24 exist in vlan 10 and vlan 20.

Just to have a straightforward reply…

Let’s start with the concept piece, which you dont need to explicitly follow, but is a decent ref. You dont need to use this explicitly, this is more about how far/close to enterprise you want, whether its for fun, for practice, whatever. From an enterprise perspective, you’ll typically have:

• Management - The only things that belongs here are network devices. Router, switches, etc, but notably not servers. This also - from just a general security perspective - should not be the default network, the vlan you get an IP from ifz you randomly connect to a port. In the enterprise, this is so people dont see the vlan switches are on, at home its just… Good practice at best.
• Services - servers you trust go here. Ones that are providing local services, not accessed by the outside (except via VPN). This could be auth services, a wiki, automation tools - proxmox servers, as an example, would go here. You may also put a jump service here - a single VM with access to management and logging, so that this becomes the only logical means of access (and a physical on the router or a locked up switch for example)
• Workstations - trusted user accessible devices would go here. Your desktop, laptop, etc go here. If an ssid is associated to this network, its typically hidden.
• IoT (no internet) - IoT devices you dont fully trust (as in, pretty much any IoT device) will get put into a VLAN without internet access. Prevents them from phoning home, usually these are closed off devices. Again, not a requirement for home use, but for personal privacy not a bad choice. This became a problem more recently in the enterprise with people buying more consumer-ish stuff at the direction of someone in C Suite who wants their office to behave like their home office. Also put your TV here. Seriously, don’t give smart tvs internet access. Block them and plug in a Linux box or something.
• Guest - Where everyone else goes, a guest vlan with internet only access. Ideally they will each get NATd and can’t see each other either. If you want these guests to be able to cast/airplay/etc though, you also would want/have:
• Media Services VLAN - this is where you would have a Chromecast, AppleTV, mersive solstice pod, airparrot, crestron air media, etc. So your receiving device lives here, in the one vlan you allow some bonjour, and allow men’s forwarding from workstation and guest to both hit this network (and its devices). Security risk. Manageable, but a risk.

There are MANY variations and unique versions of this. This is more or less a typical enterprise with we home media uses mixed in.

Now for structure purposes, you basically would have:

• Management is inaccessible by anything not a switch, with the exception of that one locked down physical port and maybe that jump VM.
• Each VLAN has its own gateway, each gateway is also NTP and DNS. You then have the upstream DNS provider be your pihole (or technitium, or pihole container, etc - I have 3 that I use so something is always up. DNS is not priority ordering, diff conversation, but having multiple is a good idea. Now your devices get their DNS from the gateway IP, and that gets it from your pihole, so you dont need to expose your pihole to those devices directly
• guest has access to NOTHING. Just internet. Maybe the media services if you’re into that sort of thing.
• IoT can be accessed from other vlans, but should have access to nothing else. As in, initiated from outside (workstation, services, etc) passes, initiated.from inside (a roomba) you block.
• the rest generally doesn’t need too much security, its more device management - workstation, servers, etc.

OK so there are the generics, let’s go back to yours.

192.168.1.x - sounds like default to me. Risky to use for proxmox and network management on a vlan generic endpoints will land in. If you have a different one for default - great! Ignore this. If its management, id move Proxmox into 200 instead.

192.168.100.x - solid choice to group up your externally facing riskier stuff and funnel it all through one connection. I’d make sure when that connection goes down everything else loses connectivity - confirm that kill switch works. Bind their network interfaces to the virtual network that goes to your VPN connection (I’m assuming a docker container here).

192.168.200.x - yup, logical group, makes sense to do. I’d probably put your hypervisor here.

Now LXC vs Docker… I’d call that mostly preference. I prefer LXC. I also keep things at a stable version and upgrade when needed, not automatically. If you want automated, your best bet is docker. If you want rock stable, and d9nt mind.manual updates, LXC is great. You can automate some with ansible and the like, but that can be a lot to set up for minimal need. YMMV.

Anything I build from source (honestly, most of what I do) I put in an LXC. Anything I take someone else’s image (rare, but happens), is docker. I have a local git repo I keep synced to projects on codeberg, github, and the like, so my setups are all set to build from that local repo. Makes sure I’ve got the latest if something is taken down, but also a local spot to make changes, test, etc for anything I may push back upstream.

Hope that helps!

Edit: Forgot to talk security!

OK first off, figure out your threat model. Where would threats come from? How serious would they be? What risks are worth taking, which are not?

Security is an ogre (onion) - its got layers. For example, I have zero concern with region blocking. No one is hitting my network from China, so I’m not allowing some random to try and get in.

What I am concerned about is user credentialing for access - one login for all services, MFA is hard required, and I don’t do text/email as MFA - that’s baby town frolics levels of security, I don’t like it.

Best way to think of it is a row of bikes. A thief is going to come by and steal one. Which one will they go for?

Do you need to have 7 bike locks and encase the whole thing in concrete? Or do you need to be enough of a pain in the ass (u lock, braided steel cable or chain looped through the wheel and frame) that the other bike (with a $5 cable lock you can pop open with a bic pen).

Take a networking class. You have numerous fundamental misunderstandings and make wild assumptions on bridging gaps that has specific requirements to occur, which also requires a complete lack of any other security methods.

Take a networking class, please. You need it.

Edit: You’re mad and still down voting, I want to point out you dont even understand the link you provided.

You should probably read that. But looooooong before then, you should take an actual class on networking.

You need it.

Take a networking class instead of spewing nonsense please.

HOW WOULD YOU GET SHELL ACCESS TO HIS ROUTER FROM A FIREWALLED OFF VLAN THAT DOES NOT GAIN ACCESS TO THE MANAGEMENT VLAN THE ROUTER IS ON.

Holy crap dude.

BASIC networking.

Thats my line.

I’m also done having any sort of discussion with you, there is a fundamental misunderstanding of logical network design here, and I have no interest in correcting that. Enjoy your day.

That’s not how any of this works… At all.

No, its managed by the firewall. The existence of a VLAN does not grant it access to egress. The firewall needs to permit that behavior.

Your entire understanding of how a logical network works is wrong. I’m not trying to be a dick - this is just really bad information that you’re sharing.

Your understanding is correct.

Multiple routers is irrelevant and ridiculous.

You are aware that a firewall rule is how you would address - in software, with logic - someone trying to get from VLAN C to VLAN A, right?

That its part of the method you’d use as a layer of security to prevent someone gaining access to.your router?

Assuming the router is compromised from the start is similarly just nutso.
