Not sure TBH. I’m looking into this.

Not sure why you had trouble on the image. Please take a look at this solution guide – it worked for me.

I guess you were trying to do it via the AWS console, unlike the solution suggested by Rob which does it all from the lab terminal. As you can probably tell from the github solution, there are many steps to this problem.

  • To create a public subnet requires all of this
    1. Create an Internet Gateway and associate with the VPC
    2. Create the subnet
    3. Create a route table for the subnet with an entry for 0.0.0.0/0 that points to the internet gateway
      These steps are what makes the subnet public.
  • Amazon Linux 2 is deprecated and will be completely retired at the end of June (I asked Engineering to update the instructions). The default option when launching instance is now Amazon Linux 2023. This is still fine, but when configuring NAT you will also have to install iptables via yum as it isn’t on this image by default.
  • You must create a custom security group for the NAT instance that allows external connections or you will not be able to connect to it to configure iptables.

Hi @sherdil,
The doc has been updated, you can use it as a reference. You can perform the task via AWS console as well, however make sure you don’t miss any step.

As Srikanth points out, we’ve updated a few things. The main things are:

  • We now use Amazon Linux 2023 rather than Amazon Linux 2
  • You need to install iptables on nat-instance, because AL 2023 does not do that by default.
  • The iptables code is a little different, because the main interface on the virtual is now enX0, rather than eth0 as it used to be.

The new guide covers these things, and is a good way to figure out the task.
