Проблема с NAT при совпадении портов

В dstnat, если dst-port == to-port по проброс порта не работает. Хост назначения в локальной сети получает пакет, но ответ не доходит до хоста, который запрашивает.

Если меняю dst-port на другой, не совпадающий с to-port, все работает.

Не пойму в чем проблема.

1. 8081->8080 работает

2. 8082->8080 работает

3. 8080->8080 не работает

4. 8081->8081 не работает

На хосте назначения конечно менял слушающий порт сервиса.
