Как поднять локальный прокси

bash и iptables

3proxy, parent поддерживает random.

Не могли показать пример конфига? в гугле и на офф сайте 3proxy не смог найти как перенаправлять с прокси на рандомный parent

Читаю мануал с выражением, беру дорого:

parent <weight> <type> <ip> <port> <username> <password>
this command must follow «allow» rule. It extends last allow rule to build proxy chain. Proxies may be grouped. Proxy inside the group is selected randomly. If few groups are specified one proxy is randomly picked from each group and chain of proxies is created (that is second proxy connected through first one and so on). Weight is used to group proxies. Weigt is a number between 1 and 1000. Weights are summed and proxies are grouped together untill weight of group is 1000. That is:
allow *
parent 500 socks5 192.168.10.1 1080
parent 500 connect 192.168.10.1 3128
makes 3proxy to randomly choose between 2 proxies for all outgoing connections. These 2 proxies form 1 group (summarized weight is 1000).
