一、前文
二、ipset知识点
2.1 ipset的增删查
2.2 ipset的ip地址修改
2.3 ipset的其他查询
三、应用实操
3.1 下载国内ip网段
3.2 新建ip集合
3.3 添加规则
3.4 有点耐心
四、测试验证
ipset是ip地址的集合。
firewalld使用ipset可以在一条规则中处理多个ip地址，执行效果更好，管理更方便。
firewalld的ipset会记录到/etc/firewalld/ipsets/目录下
#新建一个ip集合，--type=hash:ip 指定类型为 hash:ip,不允许重复ip
firewall-cmd --permanent --new-ipset=china_ip --type=hash:ip
#删除一个ip集合
firewall-cmd --permanent --delete-ipset=china_ip
#查询所有ip集合
firewall-cmd --permanent --get-ipsets#ipset添加ip
firewall-cmd --permanent --ipset=china_ip --add-entry=121.122.123.105
#从文件中添加ip到ipset
firewall-cmd --permanent --ipset=china_ip --add-entries-from-file=china_ip_list.txt
#ipset删除ip
firewall-cmd --permanent --ipset=china_ip --remove-entry=121.122.123.105
#判断ip是否存在ipset中
firewall-cmd --permanent --ipset=china_ip --query-entry=121.122.123.105
firewall-cmd --reloadmore /etc/firewalld/ipsets/china_ip.xml
#打印ipset的路径
firewall-cmd --path-ipset=china_ip --permanent
#打印ipset的内容
firewall-cmd --info-ipset=china_ip --permanent
#打印ipset的所有entry
firewall-cmd --ipset=china_ip --get-entries --permanent禁止屏蔽海外国外IP访问有两种方法
允许所有IP，禁止国外IP
禁止所有IP，允许国内IP
相对而言，禁止所有IP，允许国内IP更容易些。
因为，相比收集国内IP集合会更加容易些。
