如何测试 AWS EC2 安全组

Question

I frequently have problem with AWS EC2 Security Group. It takes me long time to figure out what goes wrong in the setting. I am wondering is there any available tool to test the security group much easier without having to manually check in AWS.

Answer 1

There's a new capability in AWS called AWS Route Analyser. With this service you can enter the instance id and your internet gateway, and it will advise you as to what (if anything) is stopping the routing of packets. See https://docs.aws.amazon.com/vpc/latest/tgw/route-analyzer.html
