**查看指定port是否有在運作**
`netstat -an|find “1883”`

**查看IP**
`ipconfig`

**轉送規則設定**
`netsh interface portproxy add v4tov4 listenaddress=192.168.50.22 listenport=1883 connectaddress=127.0.0.1 connectport=1883`
補充說明:當使用 netsh interface portproxy add 指令來設定轉發規則時，這些規則是即時生效的，但不會自動持久化保存於系統中。如果重新啟動電腦，這些規則就會被清空，這是因為 netsh 本身並不設計成在重新啟動後自動恢復規則。

**列出所有轉送規則**
`netsh interface portproxy show all`

**刪除指定轉送規則**
`netsh interface portproxy delete v4tov4 listenaddress=192.168.1.7 listenport=1883 `

**PC安裝MQTT套件**
`pip install paho-mqtt`
