Постоянный UFW-блок в Syslog

Просматривая свой syslog, я обнаружил, что 99% его состоит из UFW BLOCK-записей с 3 или 4 IP (см. ниже; отредактировано для экономии места). Нормально ли это? Что означают эти записи? Если они безопасны, как я могу исправить или предотвратить их запись в журнал? При поиске по этому вопросу выяснилось, что это как-то связано с многоадресной рассылкой, о которой я ничего не знаю. Я уже пробовал добавить входящий/исходящий доступ для 224.0.0.0/24 для UDP, а затем перезапустить UFW безрезультатно.
