e4mc
Open a Minecraft LAN server to remote players through e4mc, a networking mod.
About e4mc
e4mc is a Minecraft mod for Java Edition that lets a host share a LAN world with players outside the local network. The host installs the mod, opens the world to LAN as usual, and receives a public domain alongside the local port. Other players connect using that domain.
The mod works with vanilla clients, so players who join do not need to install it. The homepage describes e4mc as a reverse tunneling proxy that temporarily exposes a local Minecraft server to the internet. Compatibility is listed for Fabric, Forge, NeoForge and Quilt, across Minecraft versions from 1.17.x to 26.3. Pricing is not known from the source.
Key features
- Creates a public domain for a locally opened Minecraft LAN world
- Vanilla clients can join without installing the mod
- Host installs the mod; no extra software or configuration is required
- Uses the standard Open to LAN workflow in Minecraft
- Supports Fabric, Forge, NeoForge and Quilt mod loaders
- Lists compatibility with Minecraft Java Edition versions 1.17.x to 26.3
Best for: Minecraft Java Edition players who want to host a LAN world for friends on other networks without asking them to install anything.
