StarRupture Server Ports and Firewall Configuration

Proper port configuration is essential for running a StarRupture dedicated server. This guide covers the required ports and firewall setup.

Required Port

StarRupture only requires one port for the dedicated server:

The port can be changed to any available port using launch parameters.

Windows Firewall Configuration

Method 1: Windows Defender Firewall GUI

1. Open Windows Defender Firewall with Advanced Security
2. Click “Inbound Rules” in the left panel
3. Click “New Rule” in the right panel
4. Select “Port” and click Next
5. Select “UDP” and enter “7777”
6. Select “Allow the connection”
7. Check all profiles (Domain, Private, Public)
8. Name the rule “StarRupture Server” and save

Method 2: Command Line

netsh advfirewall firewall add rule name="StarRupture Server" dir=in action=allow protocol=UDP localport=7777

Linux Firewall Configuration

UFW (Ubuntu/Debian)

sudo ufw allow 7777/udp
sudo ufw reload

firewalld (CentOS/RHEL)

sudo firewall-cmd --permanent --add-port=7777/udp
sudo firewall-cmd --reload

iptables

sudo iptables -A INPUT -p udp --dport 7777 -j ACCEPT
sudo iptables-save

Router Port Forwarding

If hosting at home, you’ll need to forward the port on your router:

1. Access your router’s admin panel (usually 192.168.1.1)
2. Find the Port Forwarding section
3. Add a rule for UDP port 7777
4. Point it to your server’s local IP address
5. Save and apply changes

Using a Custom Port

To use a different game port, add the -port parameter:

StarRuptureServerEOS.exe -Log -port=7778

Remember to update your firewall rules to match the new port.

Testing Your Setup

Verify Server Is Listening

On Windows:

netstat -an | findstr "7777"

On Linux:

ss -ulnp | grep 7777

Check If Port Is Open

• Use online port checking tools (search for “port checker”)
• Have a friend try to connect
• Check server logs for connection attempts

Common Issues

Players Can’t Connect

• Verify port 7777/UDP is open and forwarded
• Check that no other application is using the port
• Disable VPN if enabled
• Ensure players are using the correct IP and port

Server Not Visible

• The server software is still experimental – direct IP connection is recommended
• Share your public IP:port with players directly
