代码如下：

iptables -I INPUT -p tcp --dport 8080 -j DROP 
iptables -I INPUT -s 111.227.231.0/24 -p tcp --dport 8080 -j ACCEPT #允许本地IP访问
iptables -I INPUT -s 69.85.93.0/24 -p tcp --dport 8080 -j ACCEPT #允许我的服务器访问
iptables -I INPUT -s 209.141.35.207 -p tcp --dport 8080 -j ACCEPT #允许我的VPS访问（VPS上有SSH代理）
service iptables save
service iptables restart

这样本地IP更换的话也可以通过Proxy swich切换到SSH代理上访问。

以下是端口，先全部封再开某些的IP
iptables -I INPUT -p tcp –dport 9889 -j DROP
iptables -I INPUT -s 192.168.1.0/24 -p tcp –dport 9889 -j ACCEPT
如果用了NAT转发记得配合以下才能生效
iptables -I FORWARD -p tcp –dport 80 -j DROP
iptables -I FORWARD -s 192.168.1.0/24 -p tcp –dport 80 -j ACCEPT

常用的IPTABLES规则如下：
只能收发邮件，别的都关闭
iptables -I Filter -m mac –mac-source 00:0F:EA:25:51:37 -j DROP
iptables -I Filter -m mac –mac-source 00:0F:EA:25:51:37 -p udp –dport 53 -j ACCEPT
iptables -I Filter -m mac –mac-source 00:0F:EA:25:51:37 -p tcp –dport 25 -j ACCEPT
iptables -I Filter -m mac –mac-source 00:0F:EA:25:51:37 -p tcp –dport 110 -j ACCEPT

IPSEC NAT 策略
iptables -I PFWanPriv -d 192.168.100.2 -j ACCEPT
iptables -t nat -A PREROUTING -p tcp –dport 80 -d $INTERNET_ADDR -j DNAT –to-destination 192.168.100.2:80
iptables -t nat -A PREROUTING -p tcp –dport 1723 -d $INTERNET_ADDR -j DNAT –to-destination 192.168.100.2:1723
