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'll try an analogy to explain better. The firewall is a lock on the door to your house. Vlans are a rule that to go from one room to another, you must go back out the locked door and back in.

So an attacker tries to come in and can't pick the lock. You are safe.

Another attacker can pick the lock and get into a room. But if they can pick the lock for one room, they can pick the same lock again and get into any other rooms because it's the same lock protecting every room in the house.
