Do my friends need to install E4mc to join my world?

No. Only the host needs E4mc. Your friends just add the public address to their server list like any other server.

Yes. E4mc uses secure tunneling and keeps your real IP hidden from connecting players. All mods on 1Minecraft are verified for safety before posting.

How many players can join my E4mc world?

It depends on your computer's performance and internet upload speed. You're essentially hosting a server on your PC, so limits are similar to any other self-hosted server. Most setups handle 5-20 players comfortably.

Will E4mc work with other mods?

Yes. E4mc only affects the networking layer for LAN games, so it doesn't conflict with gameplay mods, optimization mods like Sodium, or content mods. Other players will need the same mods if those mods add new content.

Does E4mc work with Forge servers?

E4mc is designed for Fabric. While Forge versions might exist, the mod works best with Fabric Loader and Fabric API. Check the download section for available versions.

E4mc Mod (1.20, 1.19.4) - Play LAN Without Port Forwarding

What is E4mc Mod?

Want to play Minecraft with friends who live far away without dealing with port forwarding or paying for a server? E4mc Mod is the answer. It’s a Fabric mod that turns your single-player world into a server anyone on the internet can join. The mod creates a reverse tunnel between your game and a public server, so your friends just add an address to their server list. No port forwarding, no complicated setup, no headaches.

Key Features

One-Click LAN Sharing

Open your world to LAN like normal, and E4mc automatically generates a public address. Share it with friends, and they can join from anywhere in the world.

No Port Forwarding Required

Your router stays untouched. E4mc uses reverse tunneling so friends can connect without you exposing any ports. That’s the whole point.

Zero Setup

Install the mod and you’re done. No accounts to create, no config files to mess with, nothing. When you open to LAN, E4mc handles everything automatically.

Friends Don’t Need the Mod

Only the host needs E4mc. Your friends just add the address like any other server and join.

Secure Connection

The mod uses secure tunneling, so your real IP stays hidden. Players can’t see where you’re actually hosting from.

Lightweight Performance

The mod has minimal impact on your game. It runs quietly in the background without tanking your frame rate.

Step 1: Load Your World
