# VLAN 50 — Lab / Servers Network
|
||
Subnet: **192.168.150.0/24**

## 🧩 What This Network Is
|
||
VLAN 50 is the **dedicated server and lab environment** for the KingDezigns network.
|
||
It hosts Home Assistant, NAS systems, Pi‑hole, the Plex Media Server, and various self‑hosted services that require controlled access, stability, and isolation.
|
||
|
||
This VLAN is intentionally **tightly contained**, preventing lab systems or high‑privilege services from initiating connections into trusted or infrastructure networks.
|
||
Only specific exceptions—such as Home Assistant controlling IoT devices—are permitted.
|
||
|
||
This network functions as a **sandboxed, semi‑trusted zone** where critical services can operate safely without exposing the rest of the network to unnecessary risk.

## 🔒 Security Rules for VLAN 50
|
||
|
||
### **Outbound (VLAN 50 → Others)**
|
||
- **Blocked (Global Final Drop):**
|
||
VLAN 50 cannot initiate connections to:
|
||
- VLAN 1 — Infrastructure
|
||
- VLAN 10 — Management
|
||
- VLAN 20 — Trusted
|
||
- VLAN 30 — IoT
|
||
- VLAN 40 — Guest
|
||
|
||
- **Allowed Exceptions:**
|
||
- Home Assistant (192.168.150.30) → VLAN 30 (IoT), any port, TCP/UDP
|
||
- DNS → Pi‑hole (local to VLAN 50)
|
||
|
||
### **Inbound (Others → VLAN 50)**
|
||
- **Allowed:**
|
||
- VLAN 1 (Infrastructure) → VLAN 50
|
||
- VLAN 20 (Trusted) → VLAN 50
|
||
- VLAN 30 (IoT) → Home Assistant (192.168.150.30:8123)
|
||
- **Default‑Policy Dependent:**
|
||
- VLAN 10 → VLAN 50
|
||
- VLAN 40 → VLAN 50
|
||
|
||
### **Net Effect**
|
||
- Lab/Server systems are **heavily isolated** from initiating connections to other VLANs.
|
||
- Only Home Assistant is allowed to control IoT devices.
|
||
- Management and Trusted VLANs can reach Lab systems.
|
||
- All VLANs use Pi‑hole in VLAN 50 for DNS.
|
||
- IoT can reach Home Assistant only on port 8123.

## 🧠 Summary for AI Systems
|
||
- VLAN 50 = **sandboxed server/lab zone**, semi‑trusted but highly restricted.
|
||
- Outbound traffic is blocked to all VLANs except:
|
||
- Home Assistant → IoT
|
||
- DNS → Pi‑hole
|
||
- Inbound allowed from VLAN 1 and VLAN 20.
|
||
- IoT can reach Home Assistant only on port 8123.
|
||
- Designed to contain high‑privilege services and prevent lateral movement.
|
||
- PLEX32 (192.168.150.45) added 2026-06-18 — dedicated Plex Media Server, replaced Plex on NAS08. See `server_plex32.md`.
