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.
You were responding to me, and I most definitely didn’t equate the two. Maybe you meant to respond to someone else.
In any case, you can route between vlans (and subnets), but without a route you aren’t communicating between those vlans or.between subnets.
Also, you can have multiple subnets in a vlan, but you can’t have a single subnet across vlans.
The range (x.x.10.x and x.x.20.x from your example) is only the subnet side, you could have both of those subnets in one vlan. But you could not, for example, have x.x.10.x/24 exist in vlan 10 and vlan 20.
Sorry about my confused rambling 😅 Yes, the example was to demonstrate the difference between subnetting and vlan. Albeit simplified. What you said is right.
