linux防火墙配置
1、Centos6:
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -A INPUT -s 192.168.200.178 -p all -j ACCEPT
iptables -A INPUT -s 192.168.200.195 -p all -j ACCEPT
iptables -A INPUT -s 192.168.200.180 -p all -j ACCEPT
iptables -A INPUT -s 172.16.17.71 -p all -j ACCEPT
iptables -A INPUT -s 172.16.17.72 -p all -j ACCEPT
iptables -A INPUT -s 172.16.21.6 -p all -j ACCEPT
iptables -A INPUT -s 2.0.1.0/16 -p all -j ACCEPT
iptables -P INPUT DROP 最后一步
