How to Set Up a Mount & Blade II: Bannerlord Dedicated Server

⚠️ If your system drops below 60 FPS, the server may kick you due to performance instability.⚠️

Before beginning the setup, follow these steps:

You’ll need:

• The Mount & Blade II: Dedicated Server tool from Steam
  
  
• Your start.bat file
  
  
• A tdm_config.txt file
  
  
• A server token (generated in-game)

-------------------------------------------------------------------------------------------------------

1. Open Steam.
   
   
2. In the top-left corner, click on the Library filter (defaults to “Games”) and select Tools.
   
   
3. Search for Mount & Blade II: Dedicated Server and install it.

Once installed:

• Right-click the installed tool in your Steam Library
  
  
• Click Manage > Browse Local Files

This opens the main server directory.

-------------------------------------------------------------------------------------------------------

1. Launch Mount & Blade II: Bannerlord.
   
   
2. Press Alt + ~ to open the in-game console.
   
   
3. Type: customserver.gettoken
   
   
4. Your token will be saved to: Documents\Mount & Blade II Bannerlord\Tokens

-------------------------------------------------------------------------------------------------------

Navigate to the Native module folder, typically: D:\Steam\steamapps\common\Mount & Blade II Dedicated Server\Modules\Native

Place your tdm_config.txt file here.
Open the file and change the ServerName to something unique.

-------------------------------------------------------------------------------------------------------

Go to: D:\Steam\steamapps\common\Mount & Blade II Dedicated Server\bin\Win64_Shipping_Server

Place your start.bat file here.
You’ll use this file to launch the server later.

⚠️ You can test the server now, but it likely won’t be visible to others without port forwarding ⚠️

-------------------------------------------------------------------------------------------------------

To make your server accessible online, you’ll need to forward specific ports through your router.

• Your router’s IP address
  
  
• Your router login info (usually printed on the router)
  
  
• Your PC’s local IP address

-------------------------------------------------------------------------------------------------------

1. Press Windows + R, type cmd, and hit Enter.
   
   
2. In the command prompt, type: ipconfig
   
   
3. Look for the line: IPv4 Address. . . . . : 192.168.x.x
   
   
4. Take note of this address.

-------------------------------------------------------------------------------------------------------

1. Open a web browser and type your router’s IP address in the address bar.
   
   
   • If this doesn’t work, look for the “Default Gateway” from ipconfig — that’s your router’s IP.
   
   
2. Log in using your router’s credentials (usually found beneath or behind router)
   
   
3. Navigate to Port Forwarding, Virtual Server, Firewall, or NAT settings.

-------------------------------------------------------------------------------------------------------


Note: Some routers use “Port Range” instead of External/Internal. If so, just enter the same value for both.

-------------------------------------------------------------------------------------------------------

• Save the port forwarding settings.
  
  
• Restart your router and PC.
  
  
• Launch the server using start.bat.

Your server should now be accessible to you and other players.
