过去几天我一直在与此作斗争，我试图设置一个我可以连接的 squid http 代理，并且所有流量都来自 vpn。
主机应用程序请求 ----> Squid 代理 -------> VPN -------> Internet（然后通过相同路由从这里回复）
我不确定如何做到这一点，但据我所知我的配置是正确的，但这一定不是由于服务无法联系造成的。
请帮忙

我尝试添加身份验证，但遇到了问题。
当我做一个
admin@truenas[~]$ curl -v -x http://192.168.0.35:3128 http://www.google.com/
* Trying 192.168.0.35:3128...
* connect to 192.168.0.35 port 3128 failed: No route to host
* Failed to connect to 192.168.0.35 port 3128: No route to host
* Closing connection 0
curl: (7) Failed to connect to 192.168.0.35 port 3128: No route to host
似乎失败了，我可以 ping 虚拟机和主机，双向，所以它们肯定可以互相联系。可能是我错过了一些愚蠢的事情。
