Сокеты и виртуальная машина

Необходимо связать компьютер и виртуальную машину на этом компьютере с помощью сокетов и убедиться, что связь установлена. Код написан на С в Visual studio. Компьютер и ВМ работают на windows 10. Сначала запускается cервер, а после него клиент, после чего должно установиться соединение. Если запускать сервер и клиент на компьютере ( не используя ВМ), то связь благополучно устанавливается, но если запустить сервер на ВМ, а клиент на компьютере, то соединение не происходит и за 15 минут, при этом ошибок нет. IP адрес (192.168.56.1) находил с помощью ipconfig в командой строке.
