A raw rule that matches and then accepts, drops or rejects (counter and log allowed, no interfaces) is an exception of every pair of its chain, shown as "raw: …", instead of unknown; one not for new connections is skipped like any rule. Interfaces, jumps, NAT, set and verdict maps stay unknown. The imported IPv6 neighbour discovery rule (hop limit 255) now reads as allowed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
