需要開80端口,指定IP和局域網(wǎng)
下面三行的意思:
先關(guān)閉所有的80端口
開啟ip段192.168.1.0/24端的80口
開啟ip段211.123.16.123/24端ip段的80口
# iptables -I INPUT -p tcp --dport 80 -j DROP
# iptables -I INPUT -s 192.168.1.0/24 -p tcp --dport 80 -j ACCEPT
# iptables -I INPUT -s 211.123.16.123/24 -p tcp --dport 80 -j ACCEPT
以上是臨時(shí)設(shè)置。
1.先備份iptables
# cp /etc/sysconfig/iptables /var/tmp
2.然后保存iptables
# service iptables save
3.重啟防火墻
#service iptables restart
以下是端口,先全部封再開某些的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轉(zhuǎn)發(fā)記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規(guī)則如下:
只能收發(fā)郵件,別的都關(guān)閉
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
