 - 15 Mbps network upload, but 10 is workable, 25 if you want to avoid players getting disconnected when going back to the lobby after a match
 
 **Note:** It is recommended to surpass the listed requirements. Currently the number of available servers covers the daily playerbase more than enough. If you're planning to host public servers for the community it is therefore recommended to either fill a niche (like a gamemode that is so popular that all existing servers are full) or provide a better service than existing hosts (less lag, more stable, etc.).

+You need to allow the `NorthstarLauncher.exe` in the firewall so that it can connect to the internet. By default, when you launch the server, it should pop up the Windows security alert and let you decide if the application able to connect to the network.

 ## Final checks
 
 To check whether you set everything up correctly, start the game via Northstar and go into a private match. Another Northstar user should now be able to see your server on the server browser and join it.\
