Hello! Recently I removed IPTables on my Centos 7 Droplet and since then I cannot access my server via SFTP only via the Droplet console.. I understand that It has to be some sort of Centos 7 specific Firewall problem? Any suggestions to fix this problem Is much Appreciated.. Thanks!

CentOS 7 uses firewalld to implement firewalling. To check if it is enabled, run:

sudo systemctl status firewalld

If you use the default port 22 for SSH connections, you can open that port by running:

sudo firewall-cmd --permanent --add-service=ssh
sudo firewall-cmd --reload

For more info, check out the "Configuring a Basic Firewall" section of our Additional Recommended Steps for New CentOS 7 Servers tutorial.

After setting up the bare recommended configuration for a new server, there are often some additional steps that are highly recommended in most cases. In this guide, we'll continue the initial configuration by tackling some recommended, but optional procedures.
