WSL2设置内网访问

发表于 2022-01-01 更新于 2026-04-03 分类于 WSL 阅读次数：

局域网内其他主机需要访问WSL2发布的服务时，可按下面的方法操作：

手动转发

获得虚拟机ip

如图所示虚拟机ip为172.19.25.67（每次启动都会变）

设置端口转发（需要管理员权限运行）

netsh interface portproxy add v4tov4 listenport=【宿主机windows平台监听端口】 listenaddress=0.0.0.0 connectport=【wsl2平台监听端口】 connectaddress=【wsl2平台ip】

#如：
#netsh interface portproxy add v4tov4 listenport=181 listenaddress=0.0.0.0 connectport=181 connectaddress=172.17.127.89

# 删除端口转发
netsh interface portproxy delete v4tov4 listenport=【宿主机windows平台监听端口】 listenaddress=0.0.0.0

使用脚本每次启动时进行端口转发

配置脚本

脚本代码如下：
更改ports=@ 对应的端口即可

$remoteport = bash.exe -c "ifconfig eth0 | grep 'inet '"
$found = $remoteport -match '\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}';

if( $found ){
  $remoteport = $matches[0];
} else{
  echo "The Script Exited, the ip address of WSL 2 cannot be found";
  exit;
}

#[Ports]

#All the ports you want to forward separated by coma
$ports=@(181);


#[Static ip]
#You can change the addr to your ip config to listen to a specific address
$addr='0.0.0.0';
$ports_a = $ports -join ",";


#Remove Firewall Exception Rules
#iex "Remove-NetFireWallRule -DisplayName 'WSL 2 Firewall Unlock' ";

#adding Exception Rules for inbound and outbound Rules
#iex "New-NetFireWallRule -DisplayName 'WSL 2 Firewall Unlock' -Direction Outbound -LocalPort $ports_a -Action Allow -Protocol TCP";
#iex "New-NetFireWallRule -DisplayName 'WSL 2 Firewall Unlock' -Direction Inbound -LocalPort $ports_a -Action Allow -Protocol TCP";

for( $i = 0; $i -lt $ports.length; $i++ ){
  $port = $ports[$i];
  iex "netsh interface portproxy delete v4tov4 listenport=$port listenaddress=$addr";
  iex "netsh interface portproxy add v4tov4 listenport=$port listenaddress=$addr connectport=$port connectaddress=$remoteport";
}
