Other possible route targets include VPC Peering connections (pcx-xxx), Transit Gateway (tgw-xxx), NAT Gateway (nat-xxx), Virtual Private Gateway (vgw-xxx), local resources within the same VPC (local) etc. You can tell if a subnet is public in the AWS VPC Console by reviewing the subnet's route table, for example:

May 20, 2013 · I also ran into this issue, I was unable to create a new VPC as Default-VPC nor was I able to set an existing VPC as Default-VPC (because under Action "Create Default-VPC" was disabled). But the solution is so simple, execute the cmd from CLI and it works. Make sure you have configured "aws configure" in advance. aws ec2 create-default-vpc

Dec 28, 2016 · I have found a method to verify the VPC endpoint usage. Log in to an AWS EC2 instance in the VPC; Configure the aws cli client; run aws ec2 describe-prefix-lists; for Windows PowerShell, Get-EC2PrefixList; The result should contain the the VPC endpoints prefix list ID in the attribute PrefixListId.

Possibly worth mentioning: the peering addresses for VPC Hardware VPN and AWS Direct Connect are assigned from the IPv4 Link Local address space 169.254.0.0/16. These connections have access to but are not actually "on" any VPC subnet, so they don't consume any addresses from your VPC's private address space.

I created a new VPC, a public and private subnet respectively, and then launched 2 EC2 instances into each of the subnet respectively. I also setup the security groups required for pinging (ICMP) access on the private subnet security group.

There are also other services that use a VPC, but you would only use them if you are using some of the above services, such as: Elastic Load Balancer; NAT Gateway; So, if you wish to run "completely non-vpc", then avoid services that are ...

Jan 28, 2016 · Then share private subnets via AWS resource manager (RAM) to the VPCs that need outgoing access. This has the additional benefit you have a single place where you allocate VPC IP ranges and not every account needs to bother with setting up the full VPC. More details in AWS VPC sharing best practices. This setup avoids both the Transit Gateway ...
