- [Instructor] Understanding NACLs is one thing,…and configuring them is much more fun.…Before we get started,…let's visualize what we're about to accomplish.…I've configured a VPC in the Tokyo region with two subnets,…one public and the other private.…The public subnet contains a NAT gateway…so the private subnet can get to the Internet.…I'm going to configure a NACL…that will lock down the private subnet.…Once implemented, only SSH and ICMP traffic…originating from the public subnet…will be able to get into the private subnet.…
In addition, all traffic originating…from the private subnet will be dropped.…Let's quickly review the IP space…I've set up for this exercise.…In the Tokyo region,…I have a /16 VPC in the 10 range.…Within the VPC, I have a public /24 subnet…and a private /24 subnet.…In the Frankfurt region,…I have /28 VPC in the 192 range with a single subnet.…In Tokyo, I've set up two EC2 instances.…The first one is in the public subnet,…and the second is in the private subnet.…
