Play Minecraft together without port forwarding

Wispdock’s control panel isn’t built yet. Where a step says “in your control panel”, use whatever your host gives you for files, the console and start/stop. The Minecraft side works the same everywhere.

A hosted Minecraft Java server gives the group a server address without opening a port on your home router.

Why port forwarding often fails

A Java server listens on TCP port 25565. Friends outside your house can only reach it if your router passes that port on to your PC, and that is all port forwarding does. Sometimes you can’t set it up. The router belongs to your landlord or your university, or the ISP doesn’t give you a public IPv4 address in the first place.

That last case is called CGNAT (carrier-grade NAT). Your connection shares one public address with other customers, so there’s nothing on your side to forward. To check, compare the WAN address on your router’s status page with the address a site like whatismyip shows you. If they differ, forwarding a port on your router won’t help. A WAN address between 100.64.x.x and 100.127.x.x is a sure sign of CGNAT. Some ISPs will give you a public address if you ask support. Plenty won’t.

Everything below works without touching the router.

The six options at a glance

Open to LAN

Built into Java Edition. Load your singleplayer world, press Esc, choose Open to LAN, pick the game mode and whether cheats are on, then Start LAN World. Chat shows a line like Local game hosted on port 54321. Anyone on the same network sees the world in their Multiplayer list without typing anything. Bedrock has the same idea: worlds are visible to LAN players unless you turn that off in the world settings.

The catch is in the name. It only works inside your own network, so it suits siblings on the same Wi‑Fi and nobody else. The world closes when the host quits, and the host’s PC runs the game and the server at once. It becomes useful for friends elsewhere when you combine it with a virtual LAN. In that case the LAN world doesn’t show up in their list by itself, so they add the host’s VPN address and the port from that chat line. Newer versions let you set a fixed port on the Open to LAN screen, which saves sending a new number every session.

The Essential mod

Essential is a client mod for Java Edition, available for Fabric and Forge (check its site for the versions it supports). Among other things it lets you host your singleplayer world and invite friends from an in-game friends list. No IP addresses, no ports.

It’s the least fiddly option for a group that already plays modded. The trade-offs: every player needs Essential installed and an account linked through it, the host’s PC has to stay on, and the world lives on that PC. The mod also brings a cosmetics shop and social features. Some people like those. Others don’t want them in their game.

A playit.gg tunnel

playit.gg is a tunnelling service. You run its agent on the PC that hosts the server, create a Minecraft tunnel pointing at the server’s port, and playit gives you a public address. Friends type that address into Add Server. Their traffic goes to playit’s servers and down the tunnel to your PC, so your router never needs an open port.

Friends install nothing, which is why this is the one we’d try first. It works with a proper server jar, so Paper, Fabric and modpack servers are all fine, and it has tunnels for Bedrock’s UDP port too. For a LAN world, set a fixed port on the Open to LAN screen and point the tunnel at it.

The downsides are honest ones. Every packet takes a detour through playit’s network, so ping depends on how close their nearest relay is to you and your friends. Your PC still has to stay on. The server is now on the public internet like any other, so keep online-mode=true and turn on the whitelist: the whitelist guide has the commands. playit has a free tier and sells extras on top.

Virtual LANs: Tailscale, ZeroTier, Radmin VPN

These put your PCs on one private network over the internet. Everyone installs the app and joins your network. After that, friends connect to the host’s address on that network as if you were all on the same Wi‑Fi.

• Tailscale: sign in, install it on each PC, then invite friends to your network or share just the host machine with them. The host gets an address starting with 100, which is what friends type into Add Server.
• ZeroTier: create a network in ZeroTier Central, send friends the 16-character network ID, then approve each one as they join.
• Radmin VPN: Windows only and no account needed. The host creates a network with a name and password, and friends join it.

Hamachi, which older guides mention, works the same way.

The good part is privacy. Only people on your network can reach the server, and there’s no public address for strangers to scan. Tailscale and ZeroTier connect PCs directly when they can and fall back to relays when they can’t, so ping is often close to a normal connection. The bad part is that every player has to install something, and consoles can’t run any of these apps.

If friends time out, look at the host’s firewall first. Windows often treats the VPN adapter as a public network and blocks Java on it. The can’t connect guide goes through timeouts by error message.

Realms

Realms is Mojang’s own subscription server. The owner pays, invites friends, and the world stays online when everyone logs off. Up to 10 friends can play at once. Nobody touches an IP address or a router.

Bedrock Realms is the easy answer for console players, who can’t add custom servers without workarounds. On Java, Realms runs plain vanilla: no plugins, no mods, no server files to edit, and you don’t pick the server software. If your group wants Paper plugins or a modpack, Realms can’t do it.

Rent a server

A host runs the server in a data centre with its own public address. Nobody installs anything, the world stays up when your PC is off, and you get the files and console to run any software you like. You pay monthly. Free hosts such as Aternos exist too: the server starts when someone asks for it, stops when it’s empty, and you may wait in a queue at busy times.

We’re a host, so weigh this section with that in mind, and Wispdock isn’t taking orders yet. Ping comes down to distance, so pick a location near most of your players. The server setup guide covers the rest, and connecting to your server shows friends how to add the address.

Which one we’d pick

• Two to five friends on Java, and someone’s PC is on in the evenings anyway: playit.gg. Only the host sets anything up.
• A group that doesn’t mind installing an app and wants the server private: Tailscale or ZeroTier.
• Everyone already plays modded Java with Essential: use its host feature.
• Console players in the group: Bedrock Realms. For a mixed Java and Bedrock group on PC and phone, see crossplay with Geyser.
• Nobody wants to keep a PC on, or the group keeps growing: Realms for plain vanilla, a rented server for anything else.

If you’d rather not run it at home, Wispdock’s draft plans are on the pricing page. Prices are drafts and ordering isn’t open yet.
