+# Multiplayer: Local Play/Local Wireless Guide
+
+## Ryujinx now offers multiplayer support over the internet via LDN/Local Wireless emulation in a special preview build  
+This feature emulates the "Local Play" or "Local Wireless" multiplayer mode in a particular game. Check this website for a quick reference list of games that support this multiplayer mode: http://www.lan-play.com/games  
+Give these games a try and let us know how they work!  
+For Animal Crossing: New Horizons, if you previously downloaded the Patreon save file and still have the default player name and town name, you will need to change them in order to use the multiplayer connection. Click [here](https://github.com/Ryujinx/Ryujinx/wiki/How-to-Change-Your-Player-Name-and-Town-Name-with-Animal-Crossing:-New-Horizons-Renamer) for an easy guide!
+
+Note: this feature does _**not**_ work with "Online Mode" which uses the Nintendo Switch Online service. 
+
+### Requirements:
+- an active high-speed internet connection.
+- the Ryujinx application must be enabled for inbound traffic in your firewall if you are the game host. Windows Firewall, if enabled, will pop-up prompting you to allow access. Make sure to click the button to allow it!
+- UPNP enabled in your router/firewall for P2P mode (most routers already have this enabled). Otherwise the game can still work (albeit with higher latency) using the proxy host.
+- the same game version as those you are playing with e.g. Animal Crossing: New Horizons 1.4.2; mixing game versions will _**not**_ work!
+
+### Configuration Options:
+
+Multiplayer support via P2P network hosting is already enabled by default in this preview build. In most setups, it will simply work without any configuration.
+
+**Specific Options:**
+
+_**Mode:**_  
+Set to _Ryujinx Ldn_ by default. Change the dropdown to Disabled if you wish to disable the multiplayer functionality.
+
+_**Disable P2P Network Hosting:**_  
+Unchecked by default. If you are experiencing connectivity issues and cannot get P2P to work, you may check the box labeled "Disable P2P Network Hosting (may increase latency)" to instead use the Ryujinx proxy host server.
+
+_**Username:**_  
+Set to _Player_ by default. Change this if you wish to identify yourself to others on the RyuLDN proxy server while actively in a multiplayer session.
+
+_**Network Passphrase:**_  
+Empty by default. In this state, you will be able to connect to anyone else playing the same game version as yourself. We do recommend changing this to something unique, by either creating a passphrase yourself or clicking the "Generate Random" button and sharing it with your friends to enter the same passphrase. This will protect unwanted parties from joining your game, as well as limit the number of potential rooms to join for popular games like Animal Crossing: New Horizons. We want to make sure you get to the right island!
