Подключение сервера к моей домашней сети через Strongswan (получено уведомление об ошибке INVALID_ID_INFORMATION)

Я пытаюсь установить VPN-соединение от моего корневого сервера к моей домашней сети через strongswan. Я настроил свой маршрутизатор (FritzBox 7490) для подключений VPN PSK XAUTH. VPN-соединение с моего Android-смартфона работает.

Я не могу правильно настроить strongswan. Я изучил руководство, и у меня заканчиваются идеи. Я даже не знаю, как интерпретировать журнал.

Два файла конфигурации и журнал:

/etc/strongswan/ipsec.conf

        #charondebug="ike 4, knl 4, cfg 4, mgr 4, chd 4, dmn 4, esp 4, lib 4, tnc 4"
