I have an EC2 instance running, and it belongs to a security group. If I add a new allowed connection to that security group through AWS Management Console, should that change be effective immediately? Or perhaps only after restart of the instance?
In my case, I'm trying to allow access to PostgreSQL's default port (tcp 5432 5432 0.0.0.0/0), and I'm not sure if it's the EC2 firewall or PostgreSQL's settings that are refusing the connection.
