Коллеги, нужна Ваша помощь.

Суть вопроса: есть два провайдера, которые дают серые IP (допустим, 172.16.0.0/30 & 10.1.2.0/30), у провайдера 1, есть ресурс который болтается на внешнем ИП, но доступен ИСКЛЮЧИТЕЛЬНО через свою серую сеть. У провайдера 2 есть необходимость подключения к сервису для предоставления мне услуг (если конкретно - SIP, забирать от ISP1 и заворачивать на АТС ISP2).

Собственно, что я сделал:

на интерфейсе ISP1 поставил маскарад, на интерфейсе смотрящего на ISP2 так же повесил маскарад, и сделал проброс портов с моего IP 10.1.2.2 на IP 1.2.3.4. Прописал два дефолтных маршрута на 172.16.0.1 и 10.1.2.1 с маркировками 1_SIP и 2_SIP соответственно, а так же указал маршрут на 1.2.3.4 через 172.16.0.1. На фаерволе в мангле так же указал прероутинг, что всё что идёт на 1.2.3.4 маркируется как 1_SIP.

Казалось бы, идеальная схема, обе сети за натом -> кроме конечного IP никто ничего не знает. На сервере 1.2.3.4 аутентификация по ИП должна работать, но! Про попытке соедениться - ничего не происходит. В логах Микротик послушно пишет, что от серверов из сети 10.0.0.0/24 пакет для порта 5060 получен, и отправлен на 1.2.3.4 (при этом и в фаерволе количество пакетов увеличивается, и всё хорошо), но не поступает ответной реакции, соответственно соединение не устанавливается. Ну и пакеты не возвращаются из сети ISP1.

Что не так, и куда копать? Уже неделю воюю, и не вижу ответа, который скорее всего очевиден.

Схема наглядная

а так же указал маршрут на 1.2.3.4 через 172.16.0.1

А маршрут до 10.0.0.0 через 10.1.2.х?

[dayredo]

А маршрут до 10.0.0.0 через 10.1.2.х?

Да, маршруты прописаны до их сетей.

[DRiVen]

Попробуйте sip alg отключить(ip->firewall->service-port), если не заработает - показывайте конфиг. Манглы, маршруты, нат, фильтр.

[dayredo]

Отключено.

Вот выкладки. Неактуальные (выключенные) удалил что бы глаза не мозолили. IP - заменил на случайные "на случай чего".

Соотношение с прошлой картинкой:

Megafon - ISP1

Unitel - ISP2

IP - заменил на случайные "на случай чего"

То есть вывалили принты с динамическими записями, вместо рафинированного, относительно проблемной части, экспорта конфигурации (без вагона маркированых дефолтов в белые сетки и кучи маршрутов в те же публичные адреса, да еще и через интерфейсы, на схеме отсутствующие), "на случай чего" (чего?) заменили "серую" адресацию, и теперь все это предлагается как-то скурить, угадав соответствие нескольких строк конфига со схемой?
