Proper port and firewall configuration is essential for running a Hytale dedicated server. Unlike many games that use TCP, Hytale uses the QUIC protocol over UDP<\/strong>, which requires specific configuration.<\/p>\n

Required Port<\/h2>\n\n\n\n
Port<\/th>\nProtocol<\/th>\nPurpose<\/th>\n<\/tr>\n
5520 (default)<\/td>\nUDP<\/td>\nGame traffic (QUIC protocol)<\/td>\n<\/tr>\n<\/table>\n
\nImportant:<\/strong> Hytale uses QUIC over UDP, not TCP. Make sure you configure your firewall and port forwarding for UDP specifically. TCP forwarding will not work.\n<\/div>\n

Changing the Default Port<\/h2>\n

You can change the port using the --bind<\/code> argument:<\/p>\n

java -jar HytaleServer.jar --assets PathToAssets.zip --bind 0.0.0.0:25565<\/code><\/pre>\n
Windows Firewall Configuration<\/h2>\n
Using PowerShell (Recommended)<\/h3>\n
New-NetFirewallRule -DisplayName \"Hytale Server\" -Direction Inbound -Protocol UDP -LocalPort 5520 -Action Allow<\/code><\/pre>\n
Using Windows Defender Firewall GUI<\/h3>\n
    \n
  1. Open Windows Defender Firewall with Advanced Security<\/li>\n
  2. Click “Inbound Rules” in the left panel<\/li>\n

  6. Select “Allow the connection”<\/li>\n
  7. Check all profiles (Domain, Private, Public)<\/li>\n
  8. Name the rule “Hytale Server” and save<\/li>\n<\/ol>\n
    Linux Firewall Configuration<\/h2>\n
    UFW (Ubuntu\/Debian)<\/h3>\n
    sudo ufw allow 5520\/udp\nsudo ufw reload<\/code><\/pre>\n
    firewalld (CentOS\/RHEL\/Rocky)<\/h3>\n
    sudo firewall-cmd --permanent --add-port=5520\/udp\nsudo firewall-cmd --reload<\/code><\/pre>\n

    Router Port Forwarding<\/h2>\n
    If hosting at home behind a router, you need to forward the port:<\/p>\n
      \n
    1. Access your router’s admin panel (usually 192.168.1.1 or 192.168.0.1)<\/li>\n
    2. Find Port Forwarding or Virtual Server settings<\/li>\n
