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.

Maybe I ditch my plans and just establish a VLAN for IoT and guests.

That's a good starting point. Keep IoT away from your primary vlan (for all things holy don't use VLAN ID 1). You can limit your outbound traffic for that vlan more easily if you want to cut your smart things off from the Internet.

Guest WiFi/vlan can be just a straight shot to the internet, probably no need for visitors to get to your internal services.

Eventually, you could add a DMZ where any Internet available systems like your VPN - with specific firewall rules only permitting VPN to specific locations inside your primary vlan.
