I have a Windows Server in AWS EC2. I have opened ports 80 and 443 to 0.0.0.0/0, and RDP to a private IP address for VPN access. The instance has 4 total elastic IP addresses, each mapping to a private IP address on the instance via an EC2 Network Interface. I want to close port 80 to all traffic on one of the IP addresses, but leave it open to the other three. Is this possible in AWS/VPC?
Here's the current table...
Private | Public | Ports Open
------------------------------------
10.0.0.220 | x.x.x.1 | 80, 443, 3389
10.0.0.221 | x.x.x.2 | 80, 443, 3389
10.0.0.223 | x.x.x.3 | 80, 443, 3389
10.0.0.224 | x.x.x.4 | 80, 443, 3389
Here's the goal...
Private | Public | Ports Open
------------------------------------
10.0.0.220 | x.x.x.1 | 80, 443, 3389
10.0.0.221 | x.x.x.2 | 80, 443
10.0.0.223 | x.x.x.3 | 80, 443
10.0.0.224 | x.x.x.4 | 443
Thank you!
