Hytale Firewall Rule Generator

Generate a narrow Windows Defender Firewall rule for the UDP port used by your Hytale dedicated server. The default follows the official Hytale server baseline: QUIC over UDP on port 5520.

Firewall rule nameThis is only the label shown in Windows Firewall.Hytale UDP portUse the same UDP port in the launch command and router forwarding rule.

Run the generated command in PowerShell opened as Administrator. This changes the Windows host firewall only; home hosting normally also requires a matching UDP router-forwarding rule.

Ready-to-paste PowerShell

Create the inbound UDP rule

New-NetFirewallRule -DisplayName "Hytale Server" -Direction Inbound -Protocol UDP -LocalPort 5520 -Action Allow

Verify the saved port filter

Get-NetFirewallRule -DisplayName "Hytale Server" | Get-NetFirewallPortFilter

Remove the rule later

Remove-NetFirewallRule -DisplayName "Hytale Server"

Verification scope

The UDP protocol and default port are checked against the official Hytale Server Manual. This browser tool only builds text; it cannot inspect or modify your computer, router, current firewall policy, or server process.
