VPN 建立之後 Ping 不到對方，site to site，LAN to LAN

ping不到對方的電腦

首先要查的是電腦的防火牆

因為不同網段

Windows電腦內建的防火牆都是阻擋的

Windows 防火牆整個關閉測試

有些防毒軟體也會阻擋

也要記得關閉之後才能Ping到對方的電腦

如果只開 Ping

可以直接下命令

DOS 命令提示字元 CMD 下命令

打開Ping回應

netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol=icmpv4:8,any dir=in action=allow
netsh advfirewall firewall add rule name="ICMP Allow incoming V6 echo request" protocol=icmpv6:8,any dir=in action=allow

關閉Ping回應

netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol=icmpv4:8,any dir=in action=block
netsh advfirewall firewall add rule name="ICMP Allow incoming V6 echo request" protocol=icmpv6:8,any dir=in action=block

打開網路芳鄰

netsh advfirewall firewall add rule name="Open Port 139" dir=in action=allow protocol=TCP localport=139
netsh advfirewall firewall add rule name="Open Port 445" dir=in action=allow protocol=TCP localport=445

整個Windows Firewall 關閉

netsh advfirewall set currentprofile state off

重新啟用Windows防火牆

netsh advfirewall set currentprofile state on

查看Window防火牆狀態

netsh advfirewall firewall show rule name=all
