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.
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.
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.
