OPNsense is at the heart of my home network. It manages my firewall, handles reverse proxies, virtual private network access, virtual local area networks (VLANs), tracker and advertisement blocking, DHCP leasing, and more. It’s much more than a simple firewall firmware, and the entire process of going from an ISP-provided router to a custom DIY firewall solution can take around ten minutes. If you want more control over how your network operates and enjoy open-source software, OPNsense is the way to go.
