Is the IP address resolution wrong in my EC2 instance?

问题

Hi,

The following is the result of netstat -a -o -n on my windows ec2 instance.

I see that port 80 is being used by different processes in both physical and foreign address. Does this mean that the NAT is not resolving the private and public IP address of the EC2 instance properly ?

What should I do to fix it ? On the private IP, port 80 is occupied by the node server while a chrome transaction is occupying port 80 on the foreign address.

Thanks.

Try setting DHCP Option set.

I had a problem with it. Windows Domains Machines were not resolved. At Windows networks, with AD, you must fill your domain at DHCP Option.

Look at http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_DHCP_Options.html
