Establishing proper VLAN's (lemmy.world)

Hey there selfhosted community.

I had big plans when I moved last year to finally setup my homelab with proper VLAN seperation. Well a stressfull move later I simply had no energy left and just threw my whole homelab and all my services in my main LAN with no seperation whatsoever.

In how much of a world of pain am I in now when I want to switch my homelab services over in a seperate VLAN? Any recomendations or pointers to documentation for me to go through before I decide if this is something I want to do right now?

Currently this would impact a proxmox host with 3 VM's and 1 LXC and around 20 docker images.

I usually end up doing it very simple with huge /24 ipv4 networks, f.e.
10.100.10.0/24 = VLAN 10 = User devices and purely internal servers
10.100.20.0/24 = VLAN 20 = IoT
10.100.30.0/24 = VLAN 30 = Servers that are reachable from outside
10.100.40.0/24 = VLAN 40 = Guests

The main thing for me is to ensure that traffic that wants to pass between VLANs go through my firewall/router and allow Suricata to do its IPS work.

    Pretty much this. I have several VLANS set up to segrigate traffic. For instance, one VLAN services the 'smart' TVs and gives access for my lady friend when she comes to visit. She apparently likes ads and crap hogging her screen's real estate. I have tried to get her to listen to reason, but as soon as there is an issue, it becomes an exercise in figuring out what is blocking her unfettered access. So I want that totally separate from traffic destined in and out of my server. Then I have a VLAN for some 25 security cameras, and a VLAN for server and lab operations. I make no Guest accommodations for Wi-Fi tho. You are either trusted, or not.

    It might be overly complicated, but I like to 'keep 'em separated', and it seems to work just jammy, so there's that.
