Note: The Firewall Manager is only accessible for customers with Virtual Private Servers (VPS) and Dedicated Servers. For game server customers, the firewall is pre-configured to ensure optimal security and performance. If you require any custom configurations, please contact our support team/management for assistance.

For our Dedicated Server and VPS customers, to gain access to the Firewall Manager, you need to either create a support ticket or message a member of management.

Wasabi Hosting has established itself as a reliable game hosting provider across multiple games like Minecraft, Rust, and Counter-Strike, along with providing dedicated servers for large-scale tasks. Our servers are equipped with dedicated security and performance enhancements, including our in-built firewall manager with modern tools like A2S caching.

In this article, we will explore the features and functionalities of the Firewall Manager and how to enhance your virtual server’s performance and security.

​
What is a Firewall?

A Firewall or Firewall Manager is a crucial system in a hosting environment that helps your virtual server run smoothly while protecting it from vulnerable threats and unauthorized access. It continuously monitors the data packets entering or leaving the server network, enforcing pre-defined rules to filter out malicious traffic and threats, including DDoS attacks.

​
Firewall Rules

Firewall Rules are pre-defined instructions that dictate whether to allow or block incoming or outgoing traffic based on various factors like IP addresses, ports, protocols, and traffic types. These rules safeguard your server from threats while ensuring smooth gameplay and protection of player data.

​
How to Create a Firewall Rule:

  1. Access your Firewall Manager from the Client Area and navigate to the Firewall Rules section.

  2. Click on Add to create a new Firewall Rule for your virtual server.

  3. Select the Protocol or Common Application you intend to use.

  4. Specify the Destination Port or Source IP if required.

  5. Choose the Rule from the dropdown menu to apply to your server.

  6. Save the Rule. It will be implemented on your server shortly.

Note: The Firewall Manager includes pre-defined Rules for popular games such as CSGO, Minecraft, FiveM, PalWorld, and many others. These Rules are designed to ensure optimal performance and connectivity for each game. To apply them, simply select the game-rule from the dropdown menu.

​
Application to Server Caching (A2S Caching)

A2S Caching is a mechanism used by firewalls to enhance server performance by storing responses to frequent server queries (such as player count, server details, etc.) on intermediary servers or caches. This reduces latency (ping) by minimizing the need for direct server queries.

​
How to Enable A2S Caching:

  1. Access your Firewall Management Interface from the Client Area and navigate to the A2S section.

  2. Click Add to enable A2S Caching on your virtual server.

  3. Specify the Destination Port.

  4. Save your settings, and A2S Caching will be enabled shortly after.

Common Terms & Functions

  • ICMP (Internet Control Message Protocol): Used for diagnostic and control purposes, primarily for network troubleshooting and ping requests.
  • TCP (Transmission Control Protocol): A connection-oriented protocol ensuring reliable communication through connection establishment, maintenance, and data integrity checks.
  • UDP (User Datagram Protocol): A connectionless protocol offering fast transmission without guarantees of delivery, ordering, or data integrity.
  • GRE (Generic Routing Encapsulation): A tunneling protocol encapsulating network layer protocols inside virtual point-to-point links, often used in game hosting for secure connections.
  • SRC IP (Source IP): Refers to the IP address from which incoming traffic originates. Firewall rules can specify allowed IP addresses, restricting access to trusted sources.
  • DST Port (Destination Port): Specifies the port number on the destination server (your game server) that receives incoming traffic. Each application or service operates on specific port numbers (e.g., 80 for HTTP, 443 for HTTPS, 27015 for game servers).
