Что не так с моей конфигурацией Racoon?

Я сделал конфигурацию racoon в здесь топология

И я настроил racoon левого сервера и правого сервера.

Левый сервер /etc/racoon/racoon.conf конфигурация:

remote 1001::2 {
    exchange_mode main,aggressive;
    proposal {
            encryption_algorithm 3des;
            hash_algorithm sha1;
            authentication_method pre_shared_key;
            dh_group 2;
    }
#        generate_policy off;
}
#
sainfo address 2001:123::/64[any] any address 2002:123::/64[any] any {
    pfs_group 2;
    encryption_algorithm 3des;
    authentication_algorithm hmac_md5;
    compression_algorithm deflate;
}

левый сервнер /etc/racoon/psk.txt конфигурация:

1001::2         P@ssworD

Левый сервер /etc/ipsec-tools.conf, конфигурация:

 flush;
 spdflush;

## Some sample SPDs for use racoon
#
 spdadd 2001:123::/64 2002:123::/64 any -P out ipsec
    esp/tunnel/1001::1-1001::2/require;
#
 spdadd 2002:123::/64 2001:123::/64 any -P in ipsec
    esp/tunnel/1001::2-1001::1/require;

Правый сервер также по-другому устанавливает IP-адрес, и отображается следующая ошибка.

Как я могу отправить ICMP6 компьютера 2001: 123 :: / 64 на 2002: 123 :: / 64 компьютер?
