To maintain a secure environment and protect our infrastructure, we limit the number of open ports on our web servers. This helps to reduce exposure to potential security threats.
When it comes to port permissions, it is important to distinguish between incoming and outgoing connections. The ports listed here are primarily those that your box needs to initiate outgoing connections with other services.
The ports listed here are essential for common web, database, and email functions and are open to allow necessary communication.
If you need access through other ports, our support team is available to assist with customized configurations.
List of Open Ports on Raidboxes 2.0
Here is an overview of the ports currently open on our infrastructure, along with the specific services they support:
💡 These port configurations are designed to ensure the highest level of security for our infrastructure and users. Even if certain ports are "open" for specific connections, this does not mean they are vulnerabilities for unauthorized access.
Web and HTTP Services
Ports: 80, 443, 8080, 8081, 8088
Purpose: These ports allow HTTP and HTTPS (secure HTTP) traffic, supporting standard web browsing and data transfers. Additionally, alternate HTTP ports are available for applications that may use non-standard HTTP traffic, providing flexibility for various web services.
Technical Details: These ports are configured for outbound traffic to handle different HTTP versions and protocols securely.
Database Services
Ports: 1433 (Microsoft SQL Server), 3306 (MySQL)
Purpose: These ports support connections to SQL databases, including Microsoft SQL Server and MySQL, which are widely used in many web applications for storing and retrieving data.
Technical Details: Only outbound connections on these ports are allowed, ensuring data flows only to specified database servers.
Email Services
Ports: 465, 587, 2525 (SMTP)
Purpose: These ports enable various email protocols to allow sending emails. They support both basic and secure versions of email protocols for flexibility in email server configurations.
Technical Details: Outbound access is permitted, supporting both standard and encrypted communications to maintain compatibility with a wide range of email servers.
As an increased security measure, we closed the SMTP port 25 by default on 12.06.2025.
Secure Shell (SSH)
Port: 22
Purpose: SSH allows for secure remote login and command-line access to servers, which is essential for server management and maintenance.
Technical Details: This port is configured for secure, encrypted communication to protect sensitive data during remote access sessions.
Version Control (Git)
Port: 9418
Purpose: This port is used specifically for Git, a popular version control system that helps with managing code and collaborating on projects.
Technical Details: Only outbound traffic is permitted, supporting secure access to Git repositories.
File Transfer Protocol (FTP)
Port: 21
Purpose: FTP enables the transfer of files between systems and is often used for uploading content to web servers.
Technical Details: This port is configured to handle new outbound FTP connections and is set to use a "standard" FTP helper to ensure smooth communication.
