What is NetherPortalFix?
NetherPortalFix by BlayTheNinth solves one specific multiplayer headache: walking back through a Nether portal and emerging from a different overworld portal than the one you entered. Vanilla links portals by proximity math that breaks when bases cluster together; this mod tracks the portal you actually used and returns you through it.
One job, done invisibly, on Fabric, Forge, and NeoForge — a fixture in multiplayer packs for years.
How It Works
The mod records a player's entry portal pair. On the return trip, if the destination search would pick a different portal within ambiguity range, it routes you to the remembered one.
Practical implications:
- Neighboring bases keep independent portal pairs even within vanilla's 128-block overworld search radius.
- Portal hubs in the Nether stop hijacking each other's return trips.
- No blocks, items, or commands: install on the server (and matching loaders for clients in some versions) and forget it exists.
There is deliberately nothing else to document — the absence of misrouted portals is the entire feature.
NetherPortalFix FAQ
Does NetherPortalFix change how portals link in single-player?
The benefit shows anywhere portals sit close enough to confuse vanilla linking, single-player included, but the pain point it targets is clustered multiplayer bases.
Is it needed on the client?
Server-side does the work on most versions. Check the file page for your version's exact requirements.
