e4mc Retro
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
e4mc Retro is a backport of e4mc mod, allowing you to open your Minecraft LAN world to anyone over the internet — even on older Minecraft versions.
What is e4mc?
e4mc is a reverse tunneling reverse proxy for Minecraft. In simpler terms, it's a software that allows you to temporarily expose a local Minecraft server to the internet.
How do I use it?
Simply install the mod, and Open to LAN as normal. A public domain will appear alongside the local port. Others can simply connect to the public domain to connect to your LAN server.
