firewalld限制ip访问端口,ping远程ip的8080端口

firewall-cmd --permanent --add-port=1-3389/tcp #关闭放行中端口：3389 firewall-cmd --permanent --remove-port=3389/tcp #查看firewall的状态firewall-cmd一、查看防火墙状态1、首先查看防火墙是否开启，如未开启，需要先开启防火墙并作开机自启systemctl status firewalld开启防火墙并设置开机自启systemctl start

(1)比如限制IP为192.168.0.200的地址禁止访问80端口即禁止访问机器firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.0.200" port pr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 protoc

firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="192.168.1.1" port protocol="tcp" port="8080" accept' # 允许指定IP段访问本机8080-8090端口firewall-cmd --pfirewalld的规则是默认拒绝访问systemctl start firewalld systemctl status firewalld 1. 2. 3. [root@iZ2ze30dygwd6yh7gu6lskZ ~]# systemctl start firewalld [root@iZ2ze30dyg

╯＾╰ 作为Linux服务器用户，您可以选择使用firewalld防火墙允许或限制对某些服务或IP地址的网络访问，该防火墙是CentOS/RHEL 8和大多数基于RHEL的发行版(如Fedora)的(1)开放或限制指定IP对特定端口的访问firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.0.200" port protocol="tcp" port="80" accept" fi

# 解除IP禁止访问端口remove 删除规则firewall-cmd --reload # 重载配置，生效firewall-cmd --zone=public --list-ports # 查看记录# systemctl disable f首先是开启防火墙，设置允许指定的ip访问对应得端口，具体可以参考如下1、启动firewalld systemctl
