WSL2 Ubuntu 22.04无法挂载NFS共享的问题求助

大家好，我最近碰到个棘手的问题：在WSL2运行的Ubuntu 22.04里尝试挂载NFS共享，这个操作在原生Ubuntu系统里完全正常，但在WSL2里就是行不通。

我先编辑了/etc/fstab，添加了以下配置：

172.16.0.113:/mnt/share/yocto-cache         /home/tom/cache    nfs    auto,nofail,noatime,nolock,intr,tcp,actimeo=1800    0    0

接着执行挂载命令sudo mount -vvv /home/tom/cache，得到了一串报错信息：

mount.nfs: timeout set for Thu Mar  9 07:57:54 2023
mount.nfs: trying text-based options 'nolock,intr,tcp,actimeo=1800,vers=4.2,addr=172.16.0.113,clientaddr=172.23.196.48'
mount.nfs: mount(2): Invalid argument
mount.nfs: trying text-based options 'nolock,intr,tcp,actimeo=1800,vers=4,minorversion=1,addr=172.16.0.113,clientaddr=172.23.196.48'
mount.nfs: mount(2): Operation not permitted
mount.nfs: trying text-based options 'nolock,intr,tcp,actimeo=1800,addr=172.16.0.113'
mount.nfs: prog 100003, trying vers=3, prot=6
mount.nfs: trying 172.16.0.113 prog 100003 vers 3 prot TCP port 2049
mount.nfs: prog 100005, trying vers=3, prot=6
mount.nfs: trying 172.16.0.113 prog 100005 vers 3 prot TCP port 56713
mount.nfs: mount(2): Permission denied
mount.nfs: Operation not permitted

我之前试过一个针对WSL2网桥模式的解决方案（原本是用来解决NFS挂载权限拒绝问题的），修改了端口并添加了UDP支持，但还是没效果。下面是我使用的PowerShell脚本：

$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];
    echo "IP address of WSL 2 = " $remoteport;
} 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 comma
$ports=@(111,2049);

# [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' ";
iex "Remove-NetFireWallRule -DisplayName 'WSL 2 Firewall Unlock Outbound TCP' ";
iex "Remove-NetFireWallRule -DisplayName 'WSL 2 Firewall Unlock Inbound TCP' ";
iex "Remove-NetFireWallRule -DisplayName 'WSL 2 Firewall Unlock Outbound UDP' ";
iex "Remove-NetFireWallRule -DisplayName 'WSL 2 Firewall Unlock Inbound UDP' ";

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

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";
}

有没有大佬能帮忙分析下问题出在哪？或者有没有其他可行的解决思路？
