Настройка маршрутизатора Juniper для работы с 3CX

Согласно рекомендация 3CX для полноценной работы PBX за NAT требуется осуществить forwarding ряда портов. Эти порты:

• TCP and UDP 5060 - sip
• TCP 5090 - tunnel
• UDP 9000-9049 - transport.
• Согласно рекомендациям должен быть выключен SIP ALG.

В случае с SRX серией маршрутизаторов я сделал это вот так:

Предполагается, что PBX находится в trust зоне. Версия JunOS 11.4R7.5, модель SRX 220.

Выключаем SIP ALG

set security alg sip disable;

Настраиваем сам NAT:

Настраиваем разрешения для пропуска из untrust зоны

Добавляем в адрес бук адрес нашего сервера PBX:s
et security zones security-zone trust address-book address 3cx [localPBXip]/32

Прописываем разрешения:

set security policies from-zone untrust to-zone trust policy 3cx_access match source-address any</br>
set security policies from-zone untrust to-zone trust policy 3cx_access match destination-address 3cx</br>
set security policies from-zone untrust to-zone trust policy 3cx_access match application 3cx-app-set</br>
set security policies from-zone untrust to-zone trust policy 3cx_access then permit</br>

Cтоль длительная и объёмная процедура связана с двумя вещами:

• В рамках destination NAT у Juniper невозможно применение port range, и мы вынуждены прописывать такое количество pool. Можете попробовать реализовать этот же механизм в рамках source NAT, в нём как раз, port range существует.
• У applications также отсутствует понятие port range, что приводит к таким огромным листингам конфигурации.
