                Linux中iptables中如何打开指定的端口

                例:当修改了ssh远程连接端口,如何在iptables上打开新的端口(这里将默认22端口号修改为33端口号)

                #输入命令打开33端口。

                [root@XXX ~]# iptables -I INPUT -p tcp --dport 33 -j ACCEPT
                #查看防火墙规则,发现33端口号已经打开了。
                [root@XXX ~]# iptables -nvL
                Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
                pkts bytes target prot opt in out source destination
                0 0 ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:33
                295 23186 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
                34 2310 ACCEPT icmp -- * * 0.0.0.0/0 0.0.0.0/0
                0 0 ACCEPT all -- lo * 0.0.0.0/0 0.0.0.0/0
                2342 200K REJECT all -- * * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
                Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
                pkts bytes target prot opt in out source destination
                0 0 REJECT all -- * * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
                Chain OUTPUT (policy ACCEPT 15 packets, 1412 bytes)
                pkts bytes target prot opt in out source destination
                #iptables规则已经更改,我们需要对规则进行保存。
                [root@XXX ~]# service iptables save
                iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]
                #保存完毕,重启iptables服务。
                [root@XXX ~]# service iptables restart
                iptables: Setting chains to policy ACCEPT: filter [ OK ]
                iptables: Flushing firewall rules: [ OK ]
                iptables: Unloading modules: [ OK ]

                iptables: Applying firewall rules: [ OK ]


                #同样,用此方法也可以打开web的默认端口80
