Configuring a MU server network: modem, router and Hamachi

Open ports on your modem/router to bring your server online, or use Hamachi to play on a network with friends.

For the server to leave "localhost" and accept players, the network must be configured. There are two paths: opening ports (public) or using Hamachi (closed network).

Opening ports on the router (public server)

  1. Find your server's ports (ConnectServer, GameServer, site);
  2. Access the router panel (usually 192.168.0.1 or 192.168.1.1);
  3. Look for Port Forwarding;
  4. Forward each port to the server PC's local IP;
  5. Open the same ports on the Windows firewall.
Atenção: Forward only the necessary ports. Opening too many increases your server's attack surface.

Modem in bridge vs routed mode

If you have a modem + router, sometimes you need to put the modem in bridge (or configure DMZ/forwarding in two levels) for port forwarding to work. Otherwise, traffic stops at the modem.

Nota: Combine this with a No-IP if your IP is dynamic — so players connect via a fixed domain.

Hamachi (virtual network)

Hamachi creates a VPN between PCs:

  1. Install Hamachi on the server PC and the players';
  2. Create a network and share the name/password;
  3. Everyone joins the same network and uses the Hamachi IP to connect.
Dica: Hamachi is great for tests and small groups. For a real public server, prefer opening ports or using a VPS with a static IP.

Perguntas frequentes

What is opening ports (port forwarding)?

It's telling your router to forward traffic on certain ports (the MU server's) to the PC running the server. Without it, outside players can't connect.

When should I use Hamachi?

Hamachi creates a virtual network (VPN) between PCs, useful for small group tests or playing with friends without opening ports. For a public server, opening ports or a VPS is ideal.
