I'm a new user on AWS and I'm studying with the cloud guru course for the AWS Certified Solutions Architect Associate.
While going trough the course everything worked as it was in the course, but since a few videos I have no SSH access to my EC2 instances on the default VPC.
I just finished the VPC section of the course and I see that both instances has security groups that allows communication via 80 and 22 ports.
I also checked the network access control lists and enabled both inbound and outbound traffic for 22 and 80 ports.
The VPC has an internet Gateway and the EC2 Instances have public IP's.
What am I doing wrong?
I don't remember touching nothing more than the NACL to enable 80 and 22 ports.

Your outbound NACL is preventing return traffic to your SSH host. The port rage is the destination port, not source.
The source port for the SSH daemon on your EC2 instance is an ephemeral port number, and the destination port is 22, just the opposite of your computer.
Remove the outbound NACL and everything will be fine.
Should I leave the outbound rule asDENY ALL
?
– MikeVelazco
May 30 at 18:45
If I doALLOW ALL TCP
the ssh connection is possible
– MikeVelazco
May 30 at 18:49
But if I just remove all the outbound rules and leave only theDENY ALL
or just add a rule for SSH, it stops working.

If you Deny All, then you are denying the traffic from the server to your PC. So nothing works.

But if I try to allow only Port 22, I also don't have access.
