Multiplayer Gaming Guide:Building a Virtual LAN with N2N

EasyN2N (also known as ‘Little Yellow Duck’) is a virtual networking tool specifically optimized for multiplayer gaming. Theoretically, N2N supports any game that allows LAN-based multiplayer. According to data from Bugxia, successfully tested titles include: the CS series, Red Alert 2/3, StarCraft, Warcraft III, DOTA, ARK: Survival Evolved, Civilization VI, Stellaris, Meteor Butterfly Sword, Human: Fall Flat, Worms, Left 4 Dead 1 & 2, Minecraft, Torchlight 2, and Age of Empires II.

One-Click Installation Script#

I have developed an automation script to simplify the deployment. Execute the following command:

1
wget https://script.bytesycn.com/p2p/n2n-install.sh && chmod +x n2n-server.sh && ./n2n-server.sh

One-Click Installation Script Install success

Verification#

Use the netstat -tunlp command to verify if the program is actively listening on port 9527.

N2N Client Usage Tutorial#

After launching the software, enter the IP address and port of your N2N Server. Since DHCP (Auto-IP Assignment) has been configured on the server side, you can leave the Virtual IP field blank. Alternatively, you can manually assign an IP within the same subnet (requires basic networking knowledge). Ensure the Group Name is identical for all participants; think of the Group Name as a “Room Number”—entering the same name puts everyone in the same virtual space.

Launch EasyN2N.
nter the Supernode IP and Port (e.g., 43.163.81.102:9527).
Leave the Virtual IP blank (as DHCP is enabled) or set a static IP within the subnet.
Set a unique Group Name (shared with your friends).
Click the Start button.

Once the server status displays a green checkmark and the Virtual IP is successfully assigned, the connection is established.

Once connected, you can enjoy a low-latency, virtual LAN gaming experience.

Important Notes#

Firewall Settings: If using a Cloud VPS, ensure the OS firewall (iptables/firewalld) is disabled or configured to allow the N2N port. You must also open the port in the cloud provider’s Security Group (the script uses 9527/TCP & UDP).
Consistency: Ensure all clients use the exact same Group Name.
Latency: Choose a server location that is geographically central to all players to minimize Latency and Jitter.
