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.

    if you allowed that to happen you either did not set firewall rules strict enough

    The argument was that the vlans force a device through the firewall so that the firewall can protect it. But for that to happen, like you said the firewall wasn’t strick enough or didn’t have a defense against a 0 day.

    So the vlan doesn’t do anything either way. Either the firewall works in which case you don’t need vlans to force local traffic through them a second time or they don’t work in which case again the vlan did nothing.
