Network Security • Home Lab Part 2

Network Segmentation & Security

Designed and configured a segmented home network that separates trusted users, lab systems, cameras, storage, management interfaces, and guests while allowing only the communication each zone requires.

Architecture

Security boundaries built around device purpose.

Routing & Enforcement

pfSense provides WAN routing, NAT, DNS, DHCP, inter-VLAN routing, and policy enforcement through the LAN trunk.

Switching & Wireless

The managed Omada switch carries tagged VLAN traffic. Separate HOME and LAB SSIDs are delivered through their assigned EAP650 access points.

Protected Services

The NAS and cameras use dedicated networks. Explicit rules permit required recording and trusted-user access while reducing lateral movement.

Addressing plan

Six purpose-built network zones.

VLANZoneSubnetPrimary purpose
10HOME192.168.10.0/24Trusted household devices and wireless printer
20LAB192.168.20.0/24Virtual machines, servers, and technical testing

50MGMT192.168.50.0/24pfSense, switch, controller, and AP administration
60GUEST192.168.60.0/24Internet access for visitors without internal access

Switching design

Tagged trunks and dedicated access ports.

Firewall Trunk

Switch port 18 carries VLANs 10, 20, 30, 40, 50, and 60 between the switch and pfSense.

Access-Point Uplinks

Ports 2 and 3 connect the EAP650 access points. Management uses VLAN 50 while wireless traffic is assigned to the appropriate VLAN.

Wired Infrastructure

Dedicated access-port profiles place the NAS, cameras, and management devices directly into their assigned security zones.

Access policy

Permit required services; block unnecessary paths.

HOME

  • Internet access
  • Approved access to NAS services
  • Approved camera viewing and printer access
  • No infrastructure administration by default

CAMERAS

  • Restricted from initiating access to trusted user networks
  • Allowed to send recordings to the NAS
  • Only required camera and management services permitted

NAS

  • Accessible from authorized networks only
  • Service aliases simplify storage and camera-recording rules
  • Unnecessary lateral access is blocked

MGMT

  • Dedicated administration zone
  • Access to pfSense, switch, controller, APs, NAS, and cameras
  • Separated from ordinary user and guest traffic

LAB

  • Supports virtual machines and security exercises
  • Separated from production home devices
  • Controlled access added only when testing requires it

GUEST

  • Internet access
  • No access to private subnets
  • Isolated from trusted systems and infrastructure

Troubleshooting

Problems became evidence of practical network skills.

DHCP and VLAN Connectivity

Traced missing leases and intermittent connectivity to tagging, trunk membership, PVID, and native-VLAN mismatches across pfSense and Omada.

Management Migration

Investigated legacy VLAN 1 dependencies, moved infrastructure administration toward VLAN 50, and restored controller-to-AP connectivity after addressing changes.

Firewall and Service Validation

Tested inter-VLAN rules for HOME, NAS, CAMERAS, and MGMT; used logs, connectivity tests, and packet capture to distinguish firewall issues from endpoint application issues.

Security-Control Tuning

Evaluated Suricata behavior after legitimate management traffic was affected and adjusted the implementation approach to preserve availability while improving visibility.

Outcome

A working segmented environment with documented controls.

Technical Result

Home, lab, camera, NAS, management, and guest functions operate as separate zones with deliberate access paths.

Operational Result

The environment has a documented addressing scheme, switch-port design, service requirements, and troubleshooting history for repeatable changes.

Skills Demonstrated

Network design, VLAN trunking, firewall administration, DHCP, Wi-Fi segmentation, packet analysis, IDS/IPS evaluation, testing, and technical documentation.
