My Server OS: Amazon Linux

I am trying to set up ftp. I have:

• Installed vsftpd

• open port 20-21

• open port 1024 - 1048

Basically, I followed every of these steps

• Start vsftpd service (the status indicate [ok])

I use filezilla for my ftp client.

Here is my setting/configuration:

Host: ec2-XX-XX-XXX-XX.compute-1.amazonaws.com

Port: -(blank, but I have tried 20 and 21 though)

Server Type: FTP - File Transder Protocol

Logon Type: Normal

Username: (tried root and ec2-user)

Transfer mode: Tried passive and active

I always has this error:

Status: Waiting to retry...
Status: Resolving address of ec2-XX-XX-XXX-XX.compute-1.amazonaws.com
Status: Connecting to XX.XX.XXX.XX:21...
Error:  Connection timed out
Error:  Could not connect to server

Have I missed any configuration/settings?

EDIT

After execute the /sbin/iptables -L -n

Here is the result:

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
