Trustpoint в tunnel-group, показывает какой сертификат употреблять, когда ASA1 отвечает на запрос на установку туннеля, и, используя какой CA, проверить сертификат, который инициатор соединения прислал на ASA1. Создание правил, которые указывают какое поле в сертификате обязано совпадать с указанным значением. Trustpoint указанная в crypto map, будет употребляться при инициации соединения для того чтоб найти какой сертификат употреблять для аутентификации.

Такие VPN туннели употребляются обеспечения безопасной передачи данных, голоса и видео меж 2-мя площадками к примеру, кабинетами либо филиалами. Туннель VPN создается через общедоступную сеть веб и шифруется с внедрением ряда продвинутых алгоритмов шифрования, чтоб обеспечить конфиденциальность данных, передаваемых меж 2-мя площадками. В данной для нас статье будет показано, как настроить и настроить два маршрутизатора Cisco для сотворения неизменного безопасного туннеля VPN типа «сеть-сеть» через Веб с внедрением протокола IP Security IPSec.

В рамках статьи мы предполагаем, что оба маршрутизатора Cisco имеют статический общественный IP-адрес. Во время фазы 2 создается туннель, который защищает данные. Потом в игру вступает IPSec для шифрования данных с внедрением алгоритмов шифрования и предоставляющий аутентификацию, шифрование и защиту от повторного воспроизведения. Делать будем на примере, который показан на схеме — два филиала, оба маршрутизатора филиалов подключаются к Вебу и имеют статический IP-адрес, назначенный их провайдером.

Цель состоит в том, чтоб безопасно соединить обе сети LAN и обеспечить полную связь меж ними без каких-то ограничений. Начнем с опции маршрутизатора R1 первой площадки. Это значит, что ежели у нас есть 5 различных удаленных площадок и настроено 5 различных политик ISAKMP Phase 1 по одной для каждого удаленного маршрутизатора , то, когда наш маршрутизатор пробует согласовать VPN-туннель с каждой площадкой, он вышлет все 5 политик и будет употреблять 1-ое совпадение, которое принято обоими сторонами.

Дальше мы собираемся найти Pre-Shared ключ для аутентификации с нашим партнером маршрутизатором R2 с помощью последующей команды:. Pre-Shared ключ напарника установлен на merionet , а его общественный IP-адрес — 1. Нам необходимо сделать расширенный access-list про настройку Extended ACL можно прочитать в данной статье и в нем найти какой трафф мы желаем пропускать через VPN-туннель.

В этом примере это будет трафик из одной сети в другую с Время от времени такие списки именуют crypto access-list либо interesting traffic access-list. Последующим шагом является создание набора преобразования Transform Set , используемого для защиты наших данных.

Мы окрестили его TS. Мы окрестили нашу криптографическую карту CMAP. Тег i psec-isakmp докладывает маршрутизатору, что эта криптографическая карта является криптографической картой IPsec. Хотя в данной нам карте 1.

Крайний шаг — применить криптографическую карту к интерфейсу маршрутизатора, через который выходит трафф. Сейчас перейдем к маршрутизатору Площадки 2 для завершения опции VPN. В настоящей схеме трансляция сетевых адресов NAT , быстрее всего, будет настроена для предоставления доступа в веб внутренним хостам. К этому моменту мы завершили нашу настройку, и VPN-туннель готов к запуску.

Чтоб инициировать VPN-туннель, нам необходимо вынудить один пакет пройти через VPN, и этого можно достичь, послав эхо-запрос от 1-го маршрутизатора к другому:. 1-ое эхо-сообщение icmp ping получило тайм-аут, но другие получили ответ, как и ожидалось. Время, нужное для пуска VPN-туннеля, время от времени превосходит 2 секунды, что приводит к истечению времени ожидания первого пинга.

Мы будем чрезвычайно благодарны за подробный ответ. Спасибо, что помогаете нам стать лучше! Note : If the device you are connecting to does not support IKEv2 i. I also set a keep alive value. К огорчению, на данный момент на страничке отсутствуют финальные конфигурации устройств, есть лишь пошаговое выполнение задания. Конфигурации будут, по способности, добавлены позднее. При использовании данной нам инфы обратите внимание на то, что это учебный материал.

Не все сценарии и решения могут соответствовать настоящей жизни. Когда употребляются crypto-map, нужно чтоб был указан маршрут в удаленную локальную сеть, который ведет через наружный интерфейс. Это будет тригером для шифрования трафика, так как crypto-map применяется на наружном интерфейсе.

Маршрут по умолчанию на dyn Настроить VPN меж маршрутизаторами dyn1, dyn2 и dyn3 с аутентификацией по pre-shared key. Употреблять динамические VTI на dyn2 и dyn3. Настроить crypto isakmp profile на dyn1, указать в каких вариантах он будет срабатывать и связать его с сделанным шаблонным интерфейсом. Проверить время на всех маршрутизаторах, которые будут участвовать в схеме аутентификации по сертификатам. Для того чтбоы выбать сертификат маршрутизатору, на котором находится CA, на нем нужно сгенерировать ещё одну trustpoint нельзя употреблять автоматом сделанную trustpoint :.

Настроить политику IKE с аутентификацией по сертификатам Поправить в имеющейся политике аутентификацию на сертификаты:. Xentaur — это средство для стремительной и комфортной организации гетерогенных сетей, объединяющих виртуальные машинки Xen, эмуляторы сетевых устройств, настоящие хосты и сетевые устройства, а также управлениями ими и исследования их работы.

Сети могут предназначаться как для решения учебных и исследовательских, так и для решения производственных задач. Подробнее о Xentaur.

Email required Address never made public. Name required. Blog at WordPress. Follow Following. After the GM receives this rekey, it verifies the signature using the public key that it downloaded from the KS therefore, the GM knows that it received the rekey from the KS. The following example shows how enter the command on the KS or primary KS to find only those devices that do not support GM removal:.

The above example shows that the GM with IP address You can also enter the above command on a GM. The following example shows how to enter the command on the KS or primary KS to find only those devices that do not support rekey triggering after policy replacement:.

For these devices, the primary KS sends only the triggered rekey without instructions for policy replacement. This behavior is the same as the old rekey method and ensures backward compatibility. To enable the feature for a group, you must ensure that all devices in the group are running compatible versions of the GET VPN software. The table below describes the significant fields shown in the displays. IP version for the data plane. IPv6 shows that group policies are defined in IPv6.
