How to turn off the firewall on Amazon?

Question

Amazon Web Services

how to disable firewall on amazon so that apache works, etc.

Answer 1

There are three levels of network security on AWS:
Network ACL - Works at the level of the subnet element
to open access from the entire Internet, you need to configure a rule allowing access to the instance from the address 0.0.0.0/0 and a rule allowing access from the instance to the address 0.0.0.0/0. That is , outside and outside . This is how it is set by default. If nothing has changed, then you can simply check.
Security Group - Works at the level of the network interface of your instance
To open access from the entire Internet, you need to create a rule allowing access from the address 0.0.0.0/0 to the instance, and you need to add a rule allowing access from the instance to the address 0.0.0.0/0. It is worth noting here that if you create an instance in the Amazon AWS web console, then the second rule is created automatically. If you create via API, then you need to create it.
instance firewall - runs inside your machine. Configured according to the instructions - but in general, you need to open access from 0.0.0.0/0 or disable it correctly.
I want to note that this is not the recommended way, because you immediately become vulnerable to hacker attacks. But it's up to you to decide, and the right way to search is also your task.

Answer 2
