預設是同一網段內才能使用
如果要跨網段
需在內建防火牆中變更設定
 

有時候用 VPN時，若對方沒有split tunnel，則會將default route全部指向VPN的方向，這樣有時候會拖累速度(如果對方VPN內有網管軟體)

所以這只能靠自己修改電腦上的route

參考  What is SMB signing?

Server Message Block (SMB) signing is a security feature of Windows operating systems. SMB signing ensures that the transmission and reception of files across a network are not altered in any way. As the traditional SMB authentication is vulnerable to man-in-the-middle (MITM) attacks, the secure transmission of SMB traffic is required. Implementing mutual authentication SMB signing protects a network from these attacks. The SMB signing feature adds digital signatures into SMB packets to strengthen SMB authentication.

SAM File - Holds the user names and password hashes for every account on the local machine, or domain if it is a domain controller. Simple enough wouldn't you say?

1.在開始 -> 系統管理工具 -> 具有進階安全性的Window防火牆 

2.選擇輸入規則 -> 檔案印表機共用(回應要求-ICMPv4 in)，按右鍵啟用/停用規則
