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
Symplax manages UFW rules automatically. If you add custom rules via SSH, avoid modifying ports 22, 80, and 443 — these are maintained by Symplax and may be reset during deployments.
