Networking
Ports
| Port | Service | Exposure |
|---|---|---|
| 25565/tcp | Minecraft | Internet (port-forward this on your router) |
| 8080/tcp | Dashboard | LAN/VPN only — never port-forward |
| 25575/tcp | RCON | Docker-internal only (not published at all) |
Letting friends connect
- Give the server machine a static LAN IP (router → DHCP reservation)
- Router → port forwarding → external
25565→<server-lan-ip>:25565 - Friends connect to your public IP (
curl ifconfig.me), or set up free dynamic DNS (DuckDNS et al.) so they can use a stable name likeyourname.duckdns.org
Whitelist + EasyAuth handle the "random people found my server" problem — that's what they're for.
Keeping the dashboard private
The dashboard is deliberately not hardened for the open internet (it controls Docker). Reach it from outside your LAN with Tailscale (free, ~5 minutes):
# on the server
curl -fsSL https://tailscale.com/install.sh | sh
sudo tailscale up
Install Tailscale on your phone/laptop, log into the same account, and the panel is at
http://<server-tailscale-ip>:8080 from anywhere — encrypted, invisible to everyone
else. (WireGuard works just as well if you prefer to self-host the VPN.)
Optionally pin the port binding to specific interfaces in .env/compose, and firewall
the host:
sudo ufw allow 25565/tcp
sudo ufw allow from 192.168.0.0/16 to any port 8080 proto tcp # LAN only
sudo ufw enable
If you later want the panel on a domain
Put Caddy (or Traefik/nginx) in front for TLS + an extra auth layer, and keep 8080
unpublished. This repo doesn't ship that by default — open an issue with your domain
setup and add a caddy service; the panel works fine behind a reverse proxy
(plain HTTP upstream, cookie auth).
"Is it my internet or the server?"
Performance & Lag page. Server-side lag shows as low TPS / high MSPT (affects everyone equally); player-side lag shows as high ping for that player only. The page gives a plain-English verdict and per-player ping history so you can settle the argument.
