During September 2025, Grobian enhanced the openwrt/packages repository by developing IPv6 Prefix Source IP detection and IPv6 Prefix Delegation support within the mwan3 package. This work improved load balancing and failover for multi-upstream network environments by enabling accurate IPv6 source IP handling. Grobian addressed compatibility issues in shell scripts, refining sed and grep usage to ensure error-free operation across GNU environments. The technical approach relied on Makefile and POSIX shell scripting, with a focus on robust package management and system administration. These targeted improvements contributed to more resilient networking and streamlined packaging workflows, reflecting a thoughtful and practical engineering effort.
