Feb 1, 2026February 2026 (2026-02) monthly summary for psleng/vyos-1x focused on delivering configuration enhancements, refactors, and stability improvements that reduce complexity and improve operational reliability. Key work includes rewriting the ACL TLS/flags CLI semantics and standardizing ACL node naming for consistent configurations, reorganizing NAT configuration under a new nat parent for clarity, consolidating IPsec settings under a single ipsec-acceleration flag to simplify configuration, unifying CPU settings under a single cpu-cores node with automatic core assignment, and enabling IPv6 functionality by turning on ip6-icmp-ra-punt for interfaces with DHCPv6 addresses. Additional work includes enabling GVE driver rebinding during initialization to support specific unbind/bind operations for GVE devices. These changes are traceable to explicit commits across the repository and reflect a strong emphasis on maintainability, clarity, and predictable performance in production deployments.
