linux防火墙(firewall)对端口和IP开放与限制_firewalld限制ip访问

• 启动： systemctl start firewalld
• 关闭： systemctl stop firewalld
• 查看状态： systemctl status firewalld
• 开机禁用 ： systemctl disable firewalld
• 开机启用 ： systemctl enable firewalld

重新加载配置

firewall-cmd --reload
1

重启防火墙

service firewalld restart
1

查看已经开放的端口

 firewall-cmd --list-ports
1

关闭已开放的端口,以80端口为例

firewall-cmd --permanent --remove-port=80/tcp
1

批量开放80到90之间的所有端口

firewall-cmd --zone=public --add-port=80-90/tcp --permanent
1

批量关闭80到90之间的端口

firewall-cmd --permanent --remove-port=80-90/tcp --remove-port=80-90/tcp
1

限制单个ip，限制192.168.1.100这个ip访问80端口

firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='192.168.0.200' port protocol='tcp' port='80' reject"
1

批量限制ip，限制192.168.3.x的所有ip访问80端口

firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='192.168.3.0/24' port protocol='tcp' port='80' reject"
1

允许单个ip访问80端口

firewall-cmd --permanent --remove-rich-rule="rule family='ipv4' source address='192.168.0.200' port protocol='tcp' port='80' accept"
1

批量允许多ip访问80端口

firewall-cmd --permanent --remove-rich-rule="rule family='ipv4' source address='192.168.3.0/24' port protocol='tcp' port='80' accept"
1

查看rich-rule

firewall-cmd --zone=public --list-rich-rules
