Developed and integrated an IPv6 Leases Display feature for the openwrt/packages repository, enhancing miniupnpd to surface active IPv6 leases under IPv6 PCP. This addition, implemented using Shell scripting and leveraging skills in IPv6 management and network programming, enables improved visibility and management of IPv6 deployments. The feature is enabled by default but controlled through build flags such as ENABLE_UPNPPINHOLE and CONFIG_IPV6, ensuring safe and flexible rollout. By simplifying IPv6 monitoring and reducing operational overhead, the work supports faster issue diagnosis and more efficient system configuration, delivering practical value for large-scale OpenWrt-based network environments.
