Как видно, на аплинке всё ок - запросы и ответы летают в 200 влане.
Однако на даунлинке запросы от клиента прилетают в 30 влане (и запаковываются в 200), а ответы в 200 влане не отдаются в 30 влан, а так и продолжают лететь в 200.
Соответственно, если дампить с клиента -- видны только его запросы, ответов - нет.
Подскажите пожалуйтса, почему так происходит, можно ли поправить, делаю ли я что-то не так, или это некий баг
