以管理员运行下边这个powershell脚本可以修改Windows防火墙规则，使得WSL内部的80，433，5901，6901端口暴露出来。如需暴露其它端口，可以在如下的port列表中添加或修改。
$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=@(80,443,5901,6901);
#[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

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";
}
