I try to change the SSH port from 22 to another port (218).
In AWS EC2, I shall add the rules in security group or in IP Tables?
Is there any guideline/references recommended for EC2 Security Group?
In earlier, my web unable to access - with basic security group 1. SSH - port 22 2. HTTP - port 80
with default IP tables (CentOS). The web back online when i turn off the iptables.
Suspect to be conflict between security group and iptables.
How to configure the security group with the CentOS iptables?
Anyone?
