Есть две подсети на потах 2-3 10.29.2.0/255.255.255.0 и 21-22 10.29.3.0/255.255.255.0.
С веб интерфейса пинги проходят в обе сети, но между сетями пинги не идут, пишет "заданный узел недоступен". Думаю, что это связано с маршрутизацией, но где что подкрутить не могу найти.
Помогите кто знает советом.
Спасибо.

Всё разобрался. Совсем забыл шлюзы прописать.
