Proxy
魷魚代理 - 做與我想要的完全相反的事情 - 反向允許/拒絕
我已經設置了這個 Squid 配置文件，它似乎與我想要的完全相反。它正在阻止來自 65.134.25.35 和 122.45.36.27 的流量。並允許所有其他客戶端在 80 上連接。這正常嗎？我第一次與 Squid 合作。注意：真實 IP 略有改動。

squid.conf 中 http_access 行的順序很重要。您
deny all_others在您allow myclients的 ACL 之前應用了65.134.25.35. http_access 設置按順序處理。一旦 ACL 匹配，請求將被允許或拒絕，並且規則處理將停止。myclients ACL 永遠不會做任何有用的事情，因為一切都已被拒絕。因此，您應該將您創建的任何 ACL 移到評論上方# 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
