VLAN usage under Proxmox (lemmy.world)

Hello,

Just spent a good week installing my home server. Time to pause and lookback to what I've setup and ask your help/suggestions as I am wondering if my below configuration is a good approach or just a useless convoluted approach.

I have a Proxmox instance with 3 VLAN:

Management (192.168.1.x) : the one used by proxmox host and that can access all other VLANs
Servarr (192.168.100.x) : every arr related software + Jellyfin (all LXC). All outbound connectivity goes via VPN. Cant access any VLAN
myCloud (192.168.200.X): WIP, but basically planning to have things like Nextcloud, Immich, Paperless etc...

The original idea was to allow external access via Cloudlfare tunnel but finally decided to switch back to Tailscale for "myCloud" access (as I am expected to share this with less than 5 accounts). So:

myCloud now has Tailscale running on it.
myCloud can now access Servarr VLAN

Consequently to my choice of using tailscale, I had now to use a DNS server to resolve mydomain.com:

Servarr now has pihole as DNS server reachable across all VLAN

On the top of all that I have yet another VLAN for my raspberry Pi running Vaultwarden reachable only via my personal tailscale account.

I'm open to restart things from scratch (it's fun), so let me know.

Also wondering if using LXCs is better than docker especially when it comes to updates and longer term maintenance.

They are all defined as 192.168.x.y/24 Doesn't this make them in different subnets?

Yes.

And to be clear about things, because that comment doesn't make any sense for VLANs - a VLAN can contain multiple subnets. You will not have a single subnet across multiple VLANs.

Your config is fine in that regard.
