OPNsense 25.7.11 Enhances Network Visibility With Host Discovery Feature

OPNsense 25.7.11 introduces a native host discovery service (via hostwatch) to improve MAC-based visibility and policy control, alongside extensive IPv6 kernel and networking fixes, interface handling refinements, and preparations for a larger dhcp6c update in 26.1. The release advances core hardening by reducing exec() usage, migrating ISC-DHCP to a plugin, and enhancing firewall automation, captive portal reliability, OpenVPN client export, and Unbound management, while updating Suricata to 8.0.3 for security fixes and stability improvements.
