This guide will provide you with the steps to add your server to steam favorites. Since some games server browsers do not have enough space in their list to hold all of the servers that are currently online, we recommend that you add your server to your Steam favorites.
At the top left, click on ‘View’.
Click on ‘Servers’ and head over to the ‘Favorites’ tab.
Click ‘Add Server to Favorites’.
Copy and paste your server’s IP and port in the format of IP:PORT. It is displayed in this format within your control panel in multiple locations when viewing your service.
