我安裝了ubuntu 10.04、Apache、PHP、mysql、smb。在我的 IP 本地，一切工作正常。當我嘗試從 LAN（其他電腦）存取我的電腦時，它顯示無法連接。當我從遠端電腦 ping 我的 IP 時，它 ping 正常。我可以存取互聯網和所有其他系統（http、smb）。但問題是沒有人可以在我的區域網路中遠端存取我的電腦。
我的 IP 是 192.168.85.105，我想從 192.168.85.10 訪問（Appaceh，SMB）。
是否有代理防火牆設定？
當我重新啟動系統時，同樣的問題仍然存在。現在它不起作用，請幫助我......

您是否更改了 ip 表設定？嘗試重置iptables
sudo iptables -F
或者
sudo iptables-restore
[logout require] 如果不起作用，請嘗試停用網路過濾器
sudo ufw --disable
