Network connection issue, to ec2 and FTP inside of VPC

Question

Hello I created this instance https://us-east-1.console.aws.amazon.com/ec2/home?region=us-east-1#InstanceDetails:instanceId=i-0ca9edd25728c4f62

The goal is trying to create AD user from that instance, therefore both the AD and EC2 are under the same VPC.

Question 1: I couldn't connect to the EC2 instance with RDP. I configured both the subnet and EC2 to accept RPC calls with ACL, no effect.

Question 2: eventually, I'd like to use this https://us-east-1.console.aws.amazon.com/transfer/home?region=us-east-1#/servers/s-d0e008162fc04aa1a to recieve FTP file drops from the AD's user.

Is the network correctly configured?

Thank you!

Answer

If you've configured the ACL to accept RDP inbound, have you configured outbound for ephemeral ports?
Did you configure an inbound rule on your instance's Security Group?
Is routing set up correctly?  If you're trying to RDP in over the internet your instance needs a Public IP address and your default routing needs to be to the VPC's Internet Gateway.
