firewall杂记

systemctl restart firewalld //重启防火墙firewall-cmd --reload       //重新加载防火墙配置systemctl start firewalld.service  //开启服务systemctl enable firewalld.service //开机制动启动systemctl stop firewalld.service  //关闭服务systemctl disable firewalld.service //禁止开机启动

例子：

firewall-cmd --zone=public --add-port=80/tcp --permanentfirewall-cmd --permanent --zone=public --add-service=http firewall-cmd --reload

–add-service #添加的服务

–zone #作用域

–add-port=80/tcp #添加端口，格式为：端口/通讯协议

–permanent #永久生效，没有此参数重启后失效

在每次修改 端口和服务后 /etc/firewalld/zones/public.xml 文件就会被修改 所以也可以在文件中之间修改 然后重新加载

firewall-cmd --permanent --zone=public --add-rich-rule="rule family="ipv4"  source address="192.168.0.4/24" service name="http" accept"//设置某个ip 访问某个服务firewall-cmd --permanent --zone=public --remove-rich-rule="rule family="ipv4"  source address="192.168.0.4/24" service name="http" accept" //删除配置firewall-cmd --permanent --add-rich-rule 'rule family=ipv4 source address=192.168.0.1/2 port port=80 protocol=tcp accept'    //设置某个ip访问某个端口firewall-cmd --permanent --remove-rich-rule 'rule family=ipv4 source address=192.168.0.1/2 port port=80 protocol=tcp accept'    //删除配置firewall-cmd --query-masquerade # 检查是否允许伪装IPfirewall-cmd --add-masquerade   # 允许防火墙伪装IPfirewall-cmd --remove-masquerade# 禁止防火墙伪装IPfirewall-cmd --add-forward-port=port=80:proto=tcp:toport=8080   # 将80端口的流量转发至8080firewall-cmd --add-forward-port=proto=80:proto=tcp:toaddr=192.168.1.0.1 # 将80端口的流量转发至192.168.0.1firewall-cmd --add-forward-port=proto=80:proto=tcp:toaddr=192.168.0.1:toport=8080 # 将80端口的流量转发至192.168.0.1的8080端口
