配置linux 防火墙，只有固定IP和端口才能能访问完美解决

//添加开放的端口和固定ip

vi  /etc/sysconfig/iptables

 

[root@root220156 /]# echo "unset MAILCHECK">> /etc/profile 禁止弹出发邮件

开启固定ip和端口访问配置：

-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

-A INPUT -p icmp -j ACCEPT

-A INPUT -i lo -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp -s 192.168.137.5 -m multiport --dports 10102,80 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp -s 192.168.137.21 -m multiport --dports 10102,80 -j ACCEPT
