1、编辑/etc/sysconfig/iptables，若不存在则创建

vi /etc/sysconfig/iptables

2、开启端口1022的iptables内容如下

# 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 1022 -j ACCEPT

-A INPUT -j REJECT –reject-with icmp-host-prohibited -A FORWARD -j REJECT –reject-with icmp-host-prohibited COMMIT

3、重启iptables服务

service iptables restart
