• Остальное оставить как есть
• Apply Settings

Проверка статуса подключения

Status > OpenVPN > Status

Если всё настроено правильно, должно быть:

Client: CONNECTED SUCCESS

Настройка DNS

Похоже DD-WRT не умеет обрабатывать команду dhcp-option DNS от OpenVPN-сервера, так что придётся настроить DNS вручную

Setup > Basic Setup > Network Setup > Network Address Server Settings (DHCP)

• Static DNS 1: 77.88.8.8
• Static DNS 2: 74.82.42.42
• Static DNS 3: 77.88.8.1
• Apply Settings
