Здравствуйте!
Подскажите пожалуйста, когда стоял просто apache 2.2 и в конфиге были такие строки

ProxyRequests On
ProxyVia Block
AllowCONNECT 21 25 110 443 22 554 563 5190 1080 8080 5140 5160 4000 1478 1479 1480 8008 1480>

<Proxy *>
  Order deny,allow
  deny from all
  allow from xxx.xx.xx.xx
</Proxy>

Апач работал, как прокси. Но возникла необходимость поставить nginx.
Теперь прокси перестал работать.
Как можно вернуть этот функционал?
Ниже конфиг nginx
