windows WSL 端口映射
实际应用中需要将嵌入式开发板的数据通过网络发送出去，如果 WSL 中运行的 client 要与嵌入式开发板进行通讯，则需要将 windows 的端口转发到 WSL 中，反之，如果配置了 windows 端口转发到 WSL 中，则 windows client 无法正常接收开发板的数据，这一点需要注意，需要取消端口转发 windows 端才可以正常接收数据。

Here’s an example of using the Netsh interface portproxy Windows command to add a port proxy that listens on your host port and connects that port proxy to the IP address for the WSL 2 VM.
netsh interface portproxy add v4tov4 listenport=<yourPortToForward> listenaddress=0.0.0.0 connectport=<yourPortToConnectToInWSL> connectaddress=(wsl hostname -I)
In this example, you will need to update <yourPortToForward> to a port number, for example listenport=4000. listenaddress=0.0.0.0 means that incoming requests will be accepted from ANY IP address. The Listen Address specifies the IPv4 address for which to listen and can be changed to values that include: IP address, computer NetBIOS name, or computer DNS name. If an address isn’t specified, the default is the local computer. You need to update the <yourPortToConnectToInWSL> value to a port number where you want WSL to connect, for example connectport=4000. Lastly, the connectaddress value needs to be the IP address of your Linux distribution installed via WSL 2 (the WSL 2 VM address), which can be found by entering the command: wsl.exe hostname -I.
So this command may look something like:
netsh interface portproxy add v4tov4 listenport=4000 listenaddress=0.0.0.0 connectport=4000 connectaddress=192.168.101.100
To obtain the IP address, use:
wsl hostname -Ifor the IP address of your Linux distribution installed via WSL 2 (the WSL 2 VM address)cat /etc/resolv.conffor the IP address of the Windows machine as seen from WSL 2 (the WSL 2 VM)
Using listenaddress=0.0.0.0 will listen on all
IPv4 ports
.
Using a lowercase "i" with the hostname command will generate a different result than using an uppercase "I". wsl hostname -i is your local machine (127.0.1.1 is a placeholder diagnostic address), whereas wsl hostname -I will return your local machine's IP address as seen by other machines and should be used to identify the connectaddress of your Linux distribution running via WSL 2.
