Not able to connect to internet from Amazon EC2 instance linux box

Question

In the amazon EC2 instance, i have set the set the inbound/outbound of security group to MY-IP address.

When i try to install the mysql client or some other software, its saying connection timeout.

But when i make the inbound/outbound to anywhere ie 0.0.0.0/00, then i am able to install the software.

But i don't want to expose the EC2 instance requests to everyone.

How to connect to Internet and install the software with restricted security groups. Please can u help out on this.

Answer 1

To be able to access Internet freely, you should allow outgoing network traffic.

To do so, create an outbound rule for all traffic to 0.0.0.0/0 in your EC2 Security Group. This is a default setting with EC2 and it shouldn't be a security concern.

Answer 2

In Security group, Set the outbound traffic to the below

Protocol      Port Range  Source  
All Traffic   All  All    0.0.0.0/0
