我有一个用于 http 和 ftp 连接的 squid 代理服务器，我试图使用 filezilla 打开 ftp，但总是失败并显示以下错误：
Status: Connection with proxy established, performing handshake...
Response: Proxy reply: HTTP/1.0 403 Forbidden
Error: Proxy handshake failed: ECONNRESET - Connection reset by peer
Error: Connection timed out
Error: Failed to retrieve directory listing
我嗅探了流量，发现 filezilla 正在尝试连接到不同的端口，但代理拒绝了它，这是嗅探结果的一部分
CONNECT 201.150.36.227:61179 HTTP/1.1
Host: 201.150.36.227:61179
User-Agent: FileZilla
每次都是不同的端口，所以，我没办法在 squid 中允许它，另外，我将 filezilla 设置为使用主动连接，结果相同，被动连接，再次产生相同的结果，所以，我没办法了，我需要你的帮助，也许在 filezilla 或 squid 中的设置可以完成这项工作，所以，请帮忙
这是 filezilla 的完整日志

答案1
我在 squid.conf 中添加了一个端口范围，并配置了 filezilla 来限制它将要使用的端口范围
acl SSL_ports port 50000-50010
现在，它运行良好。
谢谢
