【问题描述】：
我正在尝试设置 squid，以便通过不同的代理随机路由传出流量。这些是我从提供商处购买的代理，而不是我网络的一部分。我需要为每个 IP 地址指定一个特定端口才能连接，但无法找出正确的方法。我在 CentOS 8 上。
我尝试通过以下方式添加它们：
tcp_outgoing_address 1.0.0.01:<port>
tcp_outgoing_address 1.0.0.01/<port>
tcp_outgoing_address 1.0.0.01 <port>
tcp_outgoing_address 1.0.0.01 ::<port>
显然，这些都不起作用，实际上阻止了 squid 启动。我似乎无法在网上找到任何与我的问题类似的资源。
我可以让 squid 启动的唯一方法是完全省略端口，如下所示：
tcp_outgoing_address 1.0.0.01
但是，当我这样做并尝试访问任何 URL 时，我在浏览器中收到以下 squid 错误：
The following error was encountered while trying to retrieve the URL: http://xxxx.com/
Connection to XXX.XXX.XXX.XXX failed.
The system returned: [No Error]
这可能是因为我实际上并没有指定 squid 需要连接到每个代理的端口。澄清一下，每个代理都有不同的开放端口，即 1.0.0.01:8080、1.0.0.02:5000 ...

本质上，我的问题是如何指定每个代理需要连接的端口，或者这是否是不必要的？如果不是，是否有任何人可以确定为什么我无法连接到省略端口的任何网站？
