How to set IPAddress as "All Unassigned" using command line?

Question

I read this SetIPAndPort and tried to set the transport of RD Gateway by using powershell, but it didn't work, here is my command line:

$HTTPPort = 7443
Get-CimInstance -Namespace root/CIMV2/TerminalServices -ClassName Win32_TSGatewayServerSettings | Invoke-CimMethod -MethodName SetIPAndPort -Arguments @{TransportType = 1; Port = $HTTPPort; OverrideExisting = 1}

It returned value 2147749896, according to the Docs, it means one of the parameters to the call is not correct, so I tried to give full parameters, which including IPAddress, but whatever I tried, I just can't assign it as "All Unassigned", I must assigned an IP to pass, that's a big problem to me.

@{TransportType = 1; IPAddress = $IPAddress; Port = $HTTPPort; OverrideExisting = 1}

"0.0.0.0", "All Unassigned", "All", "Null", "None", "0", all of them can't reach my goal and returned error value 2147749896 or 2147952422.

How can I set IPAddress as All Unassigned by using SetIPAndPort command line?

I solved, use asterisk * to set IPAddress as All Unassigned, like this:

@{ TransportType = 1;
   IPAddress = "*";
   Port = 7443;
   OverrideExisting = 1
}
