My network skills are a bit shabby, I'm guessing the problem is my isp is blocking me from connecting to my aws ec2 instance? I have a default aws account with a centos image im trying to connect to. It has port 22 open in its default security group apart from that I haven't change any of the default aws config.

Unless you assign ElasticIP, the public ip of the instance will be changed after stop/start (but not after reboot).
