WSL环境下执行ufw允许Nginx HTTP流量时出现iptables filter表不存在错误的求助

嘿各位，我正在WSL环境里跟着教程安装NGINX和SSL证书，走到步骤5「允许Nginx流量」这一步时，执行命令sudo ufw allow 'nginx http'后出现了报错，具体错误内容如下：

WARN: initcaps
[Errno 2] iptables v1.8.4 (legacy): can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
Skipping adding existing rule

我特意去/etc/modprobe.d目录下查看了所有文件，没找到和iptables相关的配置文件。有没有大佬能帮忙解决这个问题呀？
