Доброго времени суток, уважаемые. Помогите понять, что не так в настройках ipsec между Racoon и Libreswan. Не поднимается туннель.
Вот так звучит ошибка на стороне racoon:
Aug 27 02:25:30 racoon: [135.181.223.220] ERROR: failed to get valid proposal. Aug 27 02:25:30 racoon: [135.181.223.220] ERROR: failed to pre-process ph1 packet (side: 1, status 1). Aug 27 02:25:30 racoon: [135.181.223.220] ERROR: phase1 negotiation failed.
Вывод ipsec status На стороне Libreswan:
