Improving and Stabilizing the Racoon2 IKE Daemon in NetBSD

NetBSD’s racoon2 IKE daemon was materially hardened with fixes for NAT traversal, IPv6, packet fragmentation, and configuration handling, making it more reliable for IPsec/L2TP VPN services behind NAT and with modern clients such as Windows, iOS, and Android. For IT organizations, the strategic value is lower operational risk and fewer brittle workarounds: the daemon now behaves more predictably, supports IPv6 by default, and is backed by automated tests that reduce regression risk in security infrastructure.
