Build your own router and firewall with Opnsense for enhanced security and control

Building your own router and firewall with Opnsense offers advanced features and improved security compared to standard consumer routers. Opnsense, based on FreeBSD, allows for easier management of network settings, including VLANs and dynamic DNS, with frequent updates for security. To start, you need suitable hardware, such as a mini PC with Intel network cards. After downloading Opnsense, you can install it using a USB stick. Basic settings include configuring the LAN interface and connecting to the internet through your existing broadband setup. Once installed, you can explore the Opnsense web interface to manage network settings and firewall rules. For advanced setups, you can create VLANs for smart home devices, ensuring they have limited access to the internet. Resources are available online for troubleshooting and further guidance.
