Automatically Blocked Ports

To prevent abuse, we automatically block certain network ports when a new server is created. 

This helps protect the infrastructure from being misused for spam, DDoS attacks, or unauthorized access.

We block the following ports by default:

• 25, 465, 587, 2525: email-related ports that are commonly used for sending spam;
• 3389, 389, 53413: ports commonly exploited for attacks (e.g., DDoS, credential theft, backdoors).

You can check which ports are blocked on your server via the server Dashboard. 

The list reflects only those ports blocked by Hostman automatically; if you manually blocked specific ports on your server, they won’t be displayed on the dashboard.

If you're using your server for legitimate purposes and need access to one of the blocked ports, contact our support team via the chat in your control panel—we’ll review your request and lift the restriction if appropriate.
