firewalld 指定IP访问某端口

1. 打开firewalld防火墙

systemctl start firewalld.service

 

2. 添加防火墙规则(对指定ip开放指定端口)

(以下红色字体需要根据实际情况修改)

允许192.168.142.166访问5432端口

firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.142.166" port protocol="tcp" port="11300" accept"

 

3. 重启防火墙,使配置生效

systemctl restart firewalld.service

 

4. 查看配置结果,验证配置

firewall-cmd --list-all

5. 删除规则

示例:

firewall-cmd --permanent --remove-rich-rule="rule family="ipv4" source address="192.168.142.166" port protocol="tcp" port="11300" accept"

systemctl restart firewalld.service
