HERE'S HOW TO DO IT:
SELECT A SERVER PROVIDER
You start by selecting a server provider. Further down this page there is a list of approved server providers. Most providers will have public servers that you can try out and we recommend that you choose one that works well for you.
SET THE RULES
As the server admin you will be able to configure the rules for the server (private or public server, maps played, game modes and much more). You will also be able to manage all the players on the server in real time.
PLAY WITH YOUR FRIENDS
When the server is set up you are ready to play. Your server will have a unique URL that you can pass along to your friends so that they can add it as a favorite in Battlelog. The server will also be available through search. Have fun!
