Linux配置防火墙添加端口(Ubuntu/Debian无法使用此方法)

 

注意:Ubuntu/Debian无法使用此方法

1、打开iptables

vi /etc/sysconfig/iptables

2、添加防火墙规则

规则参考:http://www.cnblogs.com/EasonJim/p/6847874.html

# Firewall configuration written by system-config-firewall # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -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 –dport 22 -j ACCEPT -A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT -A INPUT -m state –state NEW -m tcp -p tcp –dport 3306 -j ACCEPT -A INPUT -j REJECT –reject-with icmp-host-prohibited -A FORWARD -j REJECT –reject-with icmp-host-prohibited COMMIT 

3、防火墙生效

service iptables restart
