無法訪問 samba 伺服器

我無法連接到不在我的網路中執行 CentOS 6.4（最小安裝）的 samba 伺服器。

當我嘗試連接我的 Windows 7 客戶端時，連接失敗並顯示預設的“無法訪問”對話框。

到目前為止我已經嘗試過：

• 在我的 samba 伺服器上打開埠 137、138、139、445
• 使用 nmap 驗證埠是否打開（在 samba 伺服器上）
• 嘗試從我的客戶端遠端登錄上述埠，但連接也失敗
• 重新安裝 samba 並重新配置服務
• 暫時關閉 SELinux

桑巴版

#smbd --version
Version 3.6.9-168.el6_5

在 smb.conf 中正確設置了工作組，nmb 正在執行。

大多數 ISP 過濾 netbios 埠。如果您從 Windows 客戶端進行 nmap，您可能會看到該埠被列為filtered因為您的 ISP 阻止了它。

嘗試配置隧道協議，例如openvpn並嘗試使用此設置。
