Squid 代理 - 执行与我想要的完全相反的操作 - 反向允许/拒绝

我已经设置了这个 Squid 配置文件，但它似乎在做与我想要的完全相反的事情。它阻止了来自 65.134.25.35 和 122.45.36.27 的流量。并允许所有其他客户端在 80 上连接。这正常吗？我第一次使用 Squid。注意：真实 IP 已略有改动。

答案1

squid.conf 中 http_access 行的顺序很重要。您已deny all_others在 之前应用了 ，allow myclients这是 的 ACL。http_access65.134.25.35设置按顺序处理。一旦 ACL 匹配，请求将被允许或拒绝，规则处理将停止。myclients ACL 永远不会做任何有用的事情，因为所有内容都已被拒绝。因此，您应该将您创建的任何 ACL 移到注释 上方# And finally deny...。

# from where browsing should be allowed
http_access allow localnet
http_access allow localhost
#http_access allow whitelist
http_access allow myclients
# And finally deny all other access to this proxy
#http_access allowed
http_access deny all_others

答案2

这些 http_access 行很混乱。

您允许通过本地网络进行访问，然后拒绝所有人访问，然后再次允许单个客户端访问。
