我試圖從我在使用網路服務時經常遇到的問題中了解更多。
我有一台筆記型電腦，可以透過 ISP 路由器上網。當我嘗試透過 VPN 連接到我的工作時，我經常無法打開工作網路上的任何網路共用或任何其他資源。我正在努力了解為什麼。
當我執行 ip config 時，我看到我的 LAN IP 位址作為我的 VPN 連線：

當我嘗試 ping 工作中的伺服器（通常會回覆）時，我得到：
C:\Users\bp>ping iai.nl
Pinging iai.nl [192.168.0.0] with 32 bytes of data:
Request timed out.
1) 我的 VPN 適配器上沒有預設閘道是否正常，因為它的目的是在 VPN 子網路內路由（對於外部 IP 位址，它將使用我的 wifi 網路適配器？
2）出於某種奇怪的原因，我的筆記型電腦上的「某些東西」認為iai.nl應該在192.168.0.0上回應，但事實並非如此。這是來自 ARP 表嗎？如果沒有，誰/什麼正在嘗試 ping 192.168.0.0？
