Ubuntu pure-ftpd reply with unroutable address

On AWS Ubuntu server running pure-ftpd, when i try connecting, i get error

Status:	Server sent passive reply with unroutable address. Using server address instead.

To fix this, run

echo "30000 50000" > /etc/pure-ftpd/conf/PassivePortRange
echo "YOUR_PUBLIC_IP_HERE" > /etc/pure-ftpd/conf/ForcePassiveIP

YOUR_PUBLIC_IP_HERE = Replace with your Elastic IP or Public IP (if you don’t have an Elastic IP).

Restart pure-ftpd

systemctl stop pure-ftpd
systemctl start pure-ftpd

On AWS security groups, you need to open following ports

TCP 21
TCP 30000-50000
