Настройка Site-to-Site VPN между Edge gateway и Juniper SRX
Схема:
С подробным описанием параметров туннеля можно ознакомиться в отдельной статье
Настройка на стороне виртуального датацентра:
- Нажмите правой кнопкой на Edge Gateway и выберите Edge Gateway Services.
- На вкладке VPN включите Enable VPN (IPsec VPN service status для advanced gateway).
- Нажмите Add для добавления туннеля (”+” на вкладке IPsec VPN Sites для advanced gateway).
- Укажите название туннеля, в поле Establish VPN to: выберите a remote network, в Loca lNetworks выберите сеть виртуального дата-центра, в Peer Networks укажите внутренние сети удаленного датацентра, в Local ID адрес Edge, в Peer ID/ Peer IP - адрес удаленного маршрутизатора, выберите Encryption Protocol.
Настройка на стороне Juniper SRX:
- Создание туннельного интерфейса, зоны безопасности и статического маршрута на сеть VDC:

Примечание:
При необходимости создания множественных security-associations между более чем 2 сетями, вместо директивы ipsec vpn ike proxy-identity используется ipsec vpn traffic-selector по количеству необходимых SA. Пример: добавим подсеть 192.168.4.0/24 со стороны виртуального датацентра:
deactivate set security ipsec vpn VPN-EDGE ike proxy-identity
set security ipsec vpn VPN-EDGE traffic-selector ts1 local-ip 192.168.1.0/24 remote-ip 192.168.3.0/24
set security ipsec vpn VPN-EDGE traffic-selector ts2 local-ip 192.168.1.0/24 remote-ip 192.168.4.0/24
