Centos Stream 9 - 第二个 NIC 适配器已插入但未通过电缆发送互联网

Question

我已经创建了 centos stream 9，我打算让这个 linux 机器充当路由器，这个 linux 机器有 2 个网卡，一个连接到 wan，另一个连接到 lan，我按照下面的步骤操作，但是第二个网卡无法与其他客户端计算机共享互联网，如能得到任何帮助我将不胜感激

ens224 facing wan 
ens192 facing lan 

cat /etc/sysctl_d/ip_forward.conf
net.ipv4.ip_forward = 1

firewall-cmd --permanent --direct --passthrough ipv4 -t nat -I POSTROUTING -o ens224 -j MASQUERADE -s 192.168.1.0/24
firewall-cmd --change-interface=ens224 --zone=external --permanent
firewall-cmd --set-default-zone=internal
firewall-cmd --complete-reload
systemctl restart network && systemctl restart firewalld

• 防火墙命令--list-all--zone=external
