How to open a port on your Minecraft server

1. In your dashboard, click Open panel on the server.
2. Click Ports in the menu on the left.
3. The page lists the ports you have, with Add a port and a counter such as 2 of 10 ports.

Only the owner of the server sees the Ports tab. Team members you invited do not, whatever their permissions, so nobody else can open a way into your server.

Under the list, Other addresses of this server shows the address for Java players and, on a crossplay server, the Bedrock port. Those are already open; you do not add them here.

1. Click Add a port.
2. Under What is it for?, pick the plugin: Simple Voice Chat, Plasmo Voice, Web page, Bedrock (Geyser), Server list query, RCON or Something else. The choice fills in the protocol for you.
3. Give the port a Name you will recognise, such as Voice chat or BlueMap.
4. Check the Protocol: TCP for connections like a web page or RCON, UDP for packets like voice chat, or TCP + UDP.
5. Leave Port number on Auto, or click Choose and type a number between 30001 and 30999.
6. Choose Who may connect and the Flood protection per address (both explained below).
7. Click Open port. The panel confirms with Port 30012 is open on your address. Your server uses port 25612 for it.

Each port has two numbers. The address is what players and websites use, for example survivalsmp.mc.cheapestminecrafthosting.com:30012. The server port is the number your plugin listens on inside the server. The panel shows both on the port, with a copy button next to the address.

A server can have 10 ports. A number you used before stays yours: when you add a port again later, it comes back first.

A new port shows a Next step box. The plugin has to listen on the server port, and the server has to restart once before the port works.

Set it for me writes the number into the file and keeps a copy of the old file next to it, ending in .voor-poort. The panel then says Saved in voicechat-server.properties. Restart the server to use it. The plugin has to have run once, so its settings file exists; if not, start the server with the plugin installed first.

For the others, open the file in the Files tab or over SFTP, set the server port the panel shows, save it and restart. Edit Minecraft server files shows how.

Players never type the server port. They use the address with the public number, or, for voice chat, nothing at all: the mod reads the voice host from the server.

After the restart, click Test on the port. The panel checks it twice: From our network, straight to your server, and From the internet, through your play address like a player would.

For Bedrock (Geyser) and Server list query the test also checks the answer itself. The answer is what Server list query sends, so the plugin is running. means it is the right program.

Everyone lets every address in, which is what voice chat, a web map and Geyser need. Only these addresses lets in a list of up to 20 IPv4 addresses or ranges, one per line. Add my address puts the address you are on into the list.

RCON only opens with a list. It is a full admin console behind one password, so the panel never opens it to everyone. Add the address of the computer or bot that uses it, and nothing else.

Flood protection per address limits how hard one address can hit the port:

• Network default: the limits our network already puts on every address.
• Strict: at most 300 UDP packets per second, 20 new TCP connections per minute and 8 TCP connections at once per address.
• Custom: set each of the three numbers yourself. Leave a field empty to keep the network default for it.

• Turn off closes the port at once and keeps its number. Turn on opens it again with the same number.
• Change edits the name, protocol, who may connect and the flood limit. The number stays the same.
• Delete removes the port for good. The number stays reserved for your server and comes back first for a next port.
• History lists every change on the page, with the time and whether it worked.
• Apply all ports again sets every port on our network and on the machine again, exactly as listed. Use it when a port that should work stays closed.

Traffic on a port reaches your server only through our network. Nobody can reach the server port directly, and other customers' ports never touch yours.

Crossplay servers already have a Bedrock port, shown under Other addresses of this server. You only need the Bedrock template for a second Geyser. Crossplay between Java and Bedrock covers the normal setup.
