Question

Вероятно конечно виновата dnsmasq, но до сегодняшнего дня такого не было, перезагрузка роутера помогла.Лог ниже.

GIGA II Версия 2.08.A.11.0-4

Почему спросили про версию, у Вас переполнение таблицы conntrack. Недавно был исправлен баг с утечками записей conntrack во время сброса (flush).

Увеличение таблицы помогает?

system set net.ipv4.netfilter.ip_conntrack_max 65536

После последнего обновления, больше таких ошибок не возникало. А прошло уже 5 дней.

Увеличение таблицы не делал. Стоит ?

Причину и решение знаете, дальше на своё усмотрение.
