+# redirector
+
+Скрипт для:
+- резолва доменов (с разных DNS)
+- объединения IP / CIDR
+- генерации routing-скрипта для policy routing
+
+---
+
+## Установка
+
+```bash
+git clone https://git.pikusone.ru/pikus/redirector.git && cd redirector
+```
+
+```bash
+python3 -m venv venv
+source venv/bin/activate
+pip install -r requirements.txt
+````
+
+---
+
+## Конфиг
+
+`config.ini`
+
+```ini
+[redirector]
+threads =               # Количество потоков для dns-резолва (50)
+filename =              # Имя файла в котором списки ip, cidr и доменов (input.txt)
+script =                # Имя готового скрипта (apply_routing.sh)
+rollback_script =       # Имя скрипта для отката изменений (rollback_routing.sh) 
+exclude_cloudflare =    # Исключить адреса CloudFlare (yes, no)
+gateway =               # IP шлюза на который направлять адреса (10.10.0.1)
+table =                 # Номер таблицы маршрутизации (1010)
+run =                   # Shell команда которая выполнится после отработки скрипта (echo "lol kek")
+```
+
+---
+
+## Входной файл
+
+`input.txt`
+
+Поддерживает:
+
+```
+# комментарий
+google.com
+1.1.1.1
+8.8.8.0/24
+example.org
+```
+
+---
+
+## Запуск
+
+```bash
+venv/bin/python redirector.py
+```
+или
+```bash
+python redirector.py
+```
+
+---
+
+## Результат
+
+### ON скрипт
+
+```
+apply_routing.sh
+```
+
+Добавляет таблицу (если её нет) и маршруты в таблицу.
+
+### OFF скрипт (rollback)
+
+```
+rollback_routing.sh
+```
+
+Удаляет:
+
+* все маршруты
+* правило policy routing
+
+---
+
+## Как использовать
+
+### Включить:
+
+```bash
+./forced_vpn_ON.sh
+```
+
+### Выключить:
+
+```bash
+./forced_vpn_OFF.sh
+```
