Living Space Renovation: Network Space
Introduction
To satisfy my own needs, I built a relatively high-speed and full-featured home network environment: 2.5G intranet, NAS, and remote access.
This post records my network configuration and future plans.
Version
26/03/15 initial version
26/06/28 update: changed broadband service and adapted the network for a dedicated VR router.
Overview
The topology is shown below. The home connection is a 500M China Mobile broadband line. The optical modem is bridged into an ASUS RT-BE88U router. Two 2.5G switches, one in the bedroom and one in the living room, connect all devices. The physical layout is described in Living Space Renovation: Physical Space.

Network Layout
LAN IP allocation:
192.168.50.1 to 192.168.50.99 are static IPs.
192.168.50.100 to 192.168.50.255 are dynamic IPs.
Static allocation table:
| Segment | Use |
|---|---|
| 192.168.50.1 | Router |
| 192.168.50.2 | N100 side router |
| 192.168.50.3-19 | Home devices |
| 192.168.50.20-99 | IoT devices, such as smart lights and switches |
Hardware Layer
Router: ASUS RT-BE88U
Side router: N100 + 8GB RAM + 128GB storage
PC: 9800X3D + 24GB x 2 DDR5 + 7900XT, running Windows 11
Server: 5950X + 64GB DDR4 + 7900XTX, running Linux
NAS: UGREEN DH4300 Plus, 4TB
High-speed Wi-Fi devices:
- Quest 3
- Vision Pro
IoT control:
- Mijia smart Bluetooth gateway
- Raspberry Pi 5 (1), running Home Assistant OS
- Raspberry Pi 5 (2), running Linux with a touch screen, used to control home appliances. See DIY Monitoring Side Display.
Software Layer
LAN services:
- Home Assistant
- NAS
- Guacamole, for remote VNC, RDP, and SSH
Public access is implemented through FRP reverse proxy on an Alibaba Cloud VPS.
Summary
The current network can satisfy my daily needs. It is basically close to fully loaded for what I need now.
Future Plans
- Continue improving intranet speed, and consider SSD storage for the NAS.
- Build a 24-hour local AI service and connect it to Home Assistant.
