VLAN & WAN Isolation Router Configuration

The Security Threat of Internet-Connected IP Cameras

Standard IP security cameras are notorious targets for hackers and telemetry leaks. Many budget and enterprise cameras constantly attempt to connect to external servers in remote regions to upload crash logs, ping home, or store cloud backups without your explicit permission.

Allowing surveillance cameras to access the internet (WAN) presents a massive security vulnerability. The professional industry standard for absolute surveillance privacy is isolating your cameras on an offline, local-only subnet. Your camera feeds remain strictly inside your building, while OpticLink Pro acts as the secure local gatekeeper, receiving and managing these offline streams locally.

Step-by-Step VLAN Configuration Guide

To cut off internet access while maintaining local streaming, follow this professional router configuration workflow:

1. Create a Dedicated VLAN Subnet

In your router dashboard (e.g., pfSense, UniFi, or TP-Link Omada), navigate to Network Settings and create a new Virtual Local Area Network (VLAN). Name it Surveillance-VLAN and assign a unique subnet range, such as 192.168.40.1/24.

2. Set WAN/Internet Block Firewall Rules

Navigate to your router's Firewall Settings and add an outbound rule to block internet access:

• Action: BLOCK or REJECT
• Source: 192.168.40.1/24 (Your Surveillance VLAN Subnet)
• Destination: WAN (Wide Area Network / All External Internet)

3. Configure Inter-VLAN Routing to the Server

Create a rule to allow the camera subnet to stream video solely to the IP address of your OpticLink Pro server on your main local network (e.g., 192.168.1.15), while blocking the cameras from accessing other private personal devices on your LAN.
