This Python tool was created to help analyze AWS network connectivity.
Sometimes we spend a lot of time helping AWS users figure out why something can't reach an AWS resources via network. This tool does some basic checks, and also reports the basic information on Security Groups, Network ACLS, etc. Feedback welcome via issues on the git repo.
