В ipv4address должен быть адрес с маской - 192.168.1.2/24.

MODULE по-прежнему относится к eth0, а не к br0 - этот параметр не
надо было трогать.

Тут залип старый адрес, которого в конфигурации уже нет.

А тут из-за отсутствовавшей в br0/ipv4address маски получилось /32.

И маршрут из-за наличия старого адреса и неверной маски на br0 тоже
смотрит не на тот интерфейс.
