About E4mc Retro

e4mc Retro is a backport of the e4mc mod. It lets a player open a local Minecraft LAN world to other players over the internet, including on older Minecraft versions. The project describes e4mc as a reverse tunneling reverse proxy that temporarily exposes a local Minecraft server to the internet.

To use it, the mod is installed and the world is opened with the normal Open to LAN option. A public domain then appears alongside the local port, and other players connect to that domain. The version table lists support for Minecraft 1.6.x through 1.16.x. Versions 1.17.x and later are marked as not supported by e4mc Retro, though the original e4mc does support them. Minecraft 1.6.x must be launched with Java 8. The project is open source, and the homepage lists Apache-2.0 and MIT licenses. Pricing is unknown.
