Hi! How can I troubleshoot issues related to security groups? It is probably getting implemented via iptables but where? In the host iptables, or inside network namespace, or inside instance itself? I am running a single-node Newton. I am looking for a way to check whether the rules in my security group is actually being implemented or not. Thank you!
