Centos iptables防火墙添加IP白名单,指定IP可访问端口 vi /etc/sysconfig/iptables 以下为我虚拟机的防火墙为例(Centos 7) # sample configuration for iptables service # you can edit this manually or use system-config-firewall # please do not ask us to add additional ports/services to t
1. iptables是linux下的防火墙,同时也是服务的名称. service iptables status service iptables start service iptables stop service iptables restart 分别是查看.启动.停止.重启防火墙 2. 开放特定的端口 /etc/sysconfig/iptables 添加一行 -A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCE
我需要700至800之间的端口都能tcp访问 代码如下 复制代码 -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 700 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 701 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp
