About Nebula
Nebula closes a firewall bypass that let unparsed IPv6 protocols match TCP rules
Nebula is a peer-to-peer mesh VPN built around a certificate authority model. v1.10.0 was the pivot — IPv6 and multiple addresses in the overlay, plus a v2 ASN.1 certificate format with a unified interface for external implementations — and everything since has been consequence management. v1.11.0 shifted to the operational surface with structured slog logging, corrected firewall reject-versus-drop semantics, and Windows WFP filters by default. v1.11.1 returns to the packet classifier: IPv6 packets whose next header Nebula does not parse were being misread as TCP or UDP and matched against TCP/UDP firewall rules, and are now classified as their true protocol with no ports.
