openEuler 2203 的防火墙BUG

firewalld 后端配置为 iptables ，重新加载配置之后，整个系统网络连接就不正常了。

配置文件： /etc/firewalld/firewalld.conf

# FirewallBackend
# Selects the firewall backend implementation.
# Choices are:
#       - nftables (default)
#       - iptables (iptables, ip6tables, ebtables and ipset)
# Note: The iptables backend is deprecated. It will be removed in a future
# release.
FirewallBackend=nftables

FirewallBackend=nftables 修改为 FirewallBackend=iptables 保存、退出。
firewall-cmd --reload 之后。
整个系统网关功能就 GG了。连不上服务器。
而且 ping 127.0.0.1 也失败。

[root@localhost ~]# ping 127.0.0.1
