fe80::/10 in the IPv6 antispoof list (or your prefixes) dropped the ISP's router adverts and DHCPv6 replies in the early chain, before the ICMPv6 and DHCPv6 client built-ins could accept them: the router lost its IPv6 default route. Validation now refuses it (antispoof_link_local), the settings page says so, and the importer leaves it out with a note. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
