IPsec использует OpenSwan вместо StrongSwan

Доброе утро, парень.

Я пытался установить безопасное соединение через IPsec (StrongSwan) между моим ПК и сервером с помощью этого учебного пособия. Я установил StrongSwan как на сервере, так и на ПК, IPsec отлично работает на моем ПК, но вместо OpenSwan он используется. StrongSwan

Nov 21 10:11:15 pc-11226 systemd[1]: Started LSB: Start Openswan IPsec at boot time.

Это терпит неудачу на моем сервере, используя StrongSwan:
