LollerAgent Posted December 1, 2023 Share Posted December 1, 2023 I have my automation stuff (including C4) in it's own VLAN and I can access it just fine from other VLANs on my network. You most likely have a misconfiguration on the device that is handling your L3/inner-VLAN routing. Quote Link to comment Share on other sites More sharing options...

lippavisual Posted December 1, 2023 Share Posted December 1, 2023 I’m not seeing any need to have 2 separate VLANs at all with the equipment you listed. Id also agree that you either didn’t setup the correct rules in your firewall or don’t have any static routing setup.

Only if you overcomplicate the control system too... Particularly the moment you throw a receiver and/or projector in the mix, any good system will make it easier. In this case, not sure what the usecase would be to split up WLAN and lan as an example imho. Furthermore, that diagram impies that smarthome also has its own wifi ssid too? What happens if they add a new wireless device they want accessible in both smarthome and the standard wifi? What happens if the customer wants to swap installer? Some devices which utilise UDP also wont work particularly well over vlan too Residential has different requirements to enterprise networks.

Yes, when it’s setup properly and doesn’t require VLANs to talk to other VLANs. When this is allowed, it’s no different than just having 1 LAN. For a homeowner, it doesn’t make sense especially when they clearly don’t know much about networking. It just makes it more complicated for them.

msgreenf Posted December 3, 2023 Share Posted December 3, 2023 Vlans are very poor replacement for firewalls. They don't serve the same purpose and they are a weak security layer. They're more for traffic separation than they are real security Quote Link to comment Share on other sites More sharing options...

msgreenf Posted December 3, 2023 Share Posted December 3, 2023 Vlans, acls, firewalls all have their place. I tend to think about vlans more as traffic separation and acls and firewalls as the security constructs Andrew luecke 1 Quote Link to comment Share on other sites More sharing options...
ekohn00 Posted December 3, 2023 Share Posted December 3, 2023 VLANs are layer 2. FWs are layer 3 ACLs are firewall rules applied to a router or switch and are layer 2 and 3. Each has a reason to be used and they don't replace each other. Control4Savant and msgreenf 2 Quote Link to comment Share on other sites More sharing options...

What he's trying to say is I think is that there is practical security, and theoretical. We all know about routing and firewalls.. When installers go overboard with vlans, control4 or us often gets a call saying something isn't working over the vlan, or have stopped working. Sometimes the first troubleshooting step is "get rid of the vlan". Or sometimes, serious adjustments are needed which just removes a lot of the security anyway, or devices just get stuck "temporarily" in the wrong vlan. In this case, I'm still a bit weary that lan is split from wifi, and not sure why. And still would appreciate a explanation of why this is practical in a residential environment The question here is "how do I make control4 work between vlans" and already demonstrates that the system has likely been overcomplicated already. Hence why the initial question (where I meant 5 vlans actually, not 2), are you a large business? Quote Link to comment Share on other sites More sharing options...

Plenty of tech commercial and consumer have needed extra steps in networking config or require individual sec. rules. Thats not new and why VLANs are important, not the other way around…and even just for traffic purposes VLANS are a standard. There a bunch of useful reasons why to use them and the only “problem” is lack of knowledge which is RIPE in our industry to be putting it kindly, we should all acknowledge that point. Again, in the same point control systems are generally complete overkill for most AV which is why consumer electronics is in the state it’s in. It doesnt negate its usefulness in any way unless it’s incorrectly managed. Quote Link to comment Share on other sites More sharing options...

VLANs probably aren't needed in homes, whether they're managed correctly or incorrectly. There are just not many use cases for them at home.
