How to Host a Minecraft Server at Home Without a Public IP

You've set up a Minecraft server on your own PC, opened port 25565 in your router, and your friend still can't connect. If that's you, the problem usually isn't your configuration — it's that your ISP never gave your connection a real public IP to begin with.

Why port forwarding on your own router sometimes just doesn't work

Many home and mobile internet connections sit behind CGNAT (carrier-grade NAT) — your ISP shares one public IP across many customers, and your router only ever sees a private address. No amount of router configuration fixes this, because the problem isn't your router at all; it's that there's no public IP pointed at your connection in the first place.

The fix: forward the port somewhere that does have a public IP

A Port Forwarding plan gives you a real public IP that forwards a port of your choice to your home PC over an encrypted connection — your ISP's CGNAT never comes into it, because the traffic reaches your PC through the tunnel, not through your router's port forwarding.

Setting it up

1. Order the Starter plan (₹49/month, 3 ports — plenty for one Minecraft server)
2. Run the two connect commands on the PC running your server (see connecting your server)
3. Add a port rule: external port (whatever you want players to connect to) → internal port 25565
4. Share the public IP and port with your friends

No port forwarding needed on your router at all

Once connected, your Minecraft server is reachable through the tunnel's public IP directly — you can leave your router's own port forwarding alone entirely.
