Firewall & Network Security
Protect your servers from unauthorized access with our automated firewall management system using UFW (Uncomplicated Firewall).
Default Rules
When Symplax provisions a new server, it automatically configures a restrictive firewall policy to ensure maximum security from day one.
SSH (Port 22)
Always Allowed
HTTP (Port 80)
Web Traffic
HTTPS (Port 443)
Secure Traffic
Dynamic Port Management
When you deploy a new application, Symplax automatically opens the necessary ports on your server's firewall and configures the Nginx reverse proxy.
Important Note
Manual changes to UFW rules via SSH might be overwritten by Symplax during deployment or synchronization. We recommend managing all firewall rules through the Symplax dashboard.
