使用systemctl status iptables.service结果●
iptables.service - IPv4 firewall with iptables
Loaded: loaded (/usr/lib/systemd/system/iptables.service; enabled; vendor preset: disabled)

上面的错误是在启动ipv4 firewall时失败，可尝试关闭firewalld服务在重启iptables：
# service iptables save
#  systemctl stop firewalld  -- 关闭firewalld服务
#  systemctl disable  firewalld  --设置开机禁用firewalld
#  systemctl start iptables -- 启动iptables
#  systemctl status iptables --确认iptables状态
#  systemctl enable iptables  -- 设置iptables开机启动
#  systemctl status firewalld  --确认firewalld服务
