無法存取 samba 伺服器

我無法連接到運行 CentOS 6.4（最小安裝）的 samba 伺服器不是位於我的網路內。

當我嘗試連接 Windows 7 用戶端時，連線失敗，並顯示預設的「無法存取」對話方塊。

到目前為止我嘗試過的：

  • 在我的 samba 伺服器上開啟連接埠 137、138、139、445
  • 使用 nmap（在 samba 伺服器上）驗證連接埠是否開啟
  • 嘗試從我的客戶端遠端登入上述端口，但連接也失敗
  • 重新安裝samba並重新配置服務
  • 暫時關閉 SELinux

#smbd --version
Version 3.6.9-168.el6_5

工作組在 smb.conf 中設定正確，nmb 正在運行。

大多數 ISP 都會過濾 netbios 連接埠。如果您從 Windows 用戶端進行 nmap，您可能會看到該連接埠被列出，filtered因為您的 ISP 阻止了它。

嘗試配置隧道協議，例如openvpn並嘗試使用此設定。
