Проблемы с подключением / портом при использовании pure-ftp

Я настраиваю pure-ftp на freebsd за межсетевым экраном. На чистом ftp настроен режим passsi ftp (rangle port 50400-50600) и открытый порт межсетевого экрана с 50400-50600 (включая режим IN и Out). Но я пытаюсь использовать FTP-клиент, но не могу подключиться. Ошибка нофикации
