IoT Devices (VLAN 20 — 10.10.3.0/24)

All smart home devices have been migrated from the main LAN (192.168.0.80-94) to the IoT network (10.10.3.0/24, VLAN 20, SSID: IoTeePee). They now receive dynamic IPs via DHCP on the IoT interface. Static IPs are no longer assigned.

Pending Camera Migration (VLAN 30 — 10.10.2.0/24)

The three IP cameras (TPC100 backyard, TPC100 living room, TPC120 garden — formerly 192.168.0.92, .93, .94) will be migrated to the Camera network (10.10.2.0/24, VLAN 30) once physically reconnected. Until then, they remain on the IoT network (VLAN 20).

DHCP Configuration

Current Settings

  • DHCP Pool: 192.168.0.150 - 192.168.0.200 (51 addresses)
  • Purpose: Guest devices and temporary connections
  • Static Reservations: 20 devices with confirmed MACs

DNS Settings

  • Primary DNS: 192.168.0.11 (AdGuard Home)
  • Secondary DNS: 192.168.0.1 (OPNsense fallback)

VPN / Tailscale

IP MAC Address Purpose
100.65.128.1 e0:cb:19:60:87:70 Tailscale VLAN device
100.65.159.134 bc:24:11:be:cf:af Tailscale VLAN device (permanent)

Network Statistics

  • Total Active Devices: 33
  • VMs/Containers: 10
  • User Computers: 5 (3 PCs + 2 printers)
  • Mobile Devices: 3 (2 phones + 1 tablet)
  • TVs & Media: 3
  • Smart Home/IoT: 15 (9 Tapo + 1 Yeelight + 2 Reolink + 3 Tuya) — all on VLAN 20
  • Network Infrastructure: 1 (UniFi U7 Lite AP)
  • Hypervisors: 2
  • Static Assignments: 20 devices
  • DHCP Pool Size: 51 addresses

Known Issues

Tapo App Issues

  • Some Tapo devices may show incorrect info in app after VLAN migration
  • 3D printer plug: App showing wrong MAC, verify after print finishes
  • Resolution: Use OPNsense ARP table MACs as source of truth

Devices Needing Attention

  • Factory reset recommended for Tapo devices showing app glitches after VLAN migration

Maintenance Tasks

Regular Tasks

  • Monthly: Review DHCP leases for new unknown devices
  • Quarterly: Audit static IP assignments
  • Quarterly: Update device firmware (routers, APs, cameras)
  • Yearly: Review and optimize IP allocation scheme

Pending Tasks

  • Factory reset Tapo devices with app issues

Security Considerations

  1. Network Segmentation: VLAN 20 (IoT) and VLAN 30 (Cameras) isolate untrusted devices from the main LAN
  2. Guest Network: DHCP pool isolated from static devices
  3. Firewall Rules: OPNsense enforces strict inter-VLAN rules — IoT can only reach HA; Cameras can only reach HA and Frigate/FoundryVTT
  4. DNS Filtering: AdGuard Home provides ad/tracker blocking
  5. Remote Access: Tailscale VPN for secure remote access

Backup Strategy

What to Backup

  1. OPNsense Configuration: XML backup from web interface
  2. DHCP Reservations: CSV export (included in this repo)
  3. Network Documentation: This README and related files
  4. AdGuard Home Config: Settings and filter lists

Migration Notes

Troubleshooting

Device Not Getting Reserved IP

  1. Check MAC address in router's ARP table
  2. Verify DHCP reservation exists
  3. Release/renew DHCP lease on device
  4. Check for MAC address conflicts

Cannot Access Device

  1. Verify device is online (ping IP)
  2. Check if device changed MAC (WiFi vs Ethernet)
  3. Review firewall rules in OPNsense
  4. Check DNS resolution in AdGuard Home

IoT Device Issues

  1. Tapo devices: Check app vs ARP table for correct MAC
  2. Battery devices (water sensor): Won't always appear in ARP
  3. For offline devices: Power cycle or factory reset

Tools & Commands

Identify Device by MAC

# Online MAC lookup
curl -s "https://api.macvendors.com/5c:62:8b:8d:cb:d6"

# Or use OUI lookup
# First 6 characters (3 octets) identify manufacturer

Scan Network

# Using nmap
nmap -sn 192.168.0.0/24

# Using arp-scan (more reliable)
sudo arp-scan --interface=eth0 192.168.0.0/24

Check Current IP/MAC

# View ARP table
arp -a

# Or on OPNsense
arp -an | grep 192.168.0

Configuration Files:

  • dhcp-reservations.csv - DHCP static assignments export
  • Network Inventory.docx - Human-readable network map
  • opnsense-config.xml - OPNsense configuration backup (not in repo)
