Better way is Amazon Linux and
Enhanced Networking on Linux C3、C4、M4
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/sriov-networking.html
I think is better for performace.

http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_NAT_Instance.html#NATSG
1.1、Create instance form ami ：ami-vpc-nat-hvm choese best new
***NAT AMI***
1.2、
Check．IPv4 forwarding is enabled and ICMP redirects are disabled in /etc/sysctl.d/10-nat-settings.conf
IPv4 forwarding =1

Here have problem, so must delete POSTROUTING
sudo iptables -t nat -D POSTROUTING 1
