Play Terraria Online with Friends
The Problem
Terraria multiplayer requires either hosting a dedicated server (complex) or using Steam's invite system (unreliable for some players). Port forwarding is often needed for direct connections.
The Solution
MoleTun bypasses these issues by putting everyone on a virtual LAN. One player hosts, others join via IP—just like playing on a home network.
Setup Guide
Install MoleTun
Download and install MoleTun on all players' computers.
Create & Join Room
Host creates a room and shares the code. Friends join using the code.
Host Multiplayer in Terraria
In Terraria, select Multiplayer → Host & Play. Choose your character and world.
Friends Connect
Friends select Multiplayer → Join via IP and enter the host's MoleTun IP address.
The host's MoleTun IP is shown in the app after creating a room. Make sure everyone uses the same Terraria version.
Pro Tips
