====RD Gateway Transport Settings not editable====

When editing any settings on the TransPort Settings tab of the RD Gateway server properties you get a message saying "Unable to set transport settings":

{{:microsoft:windows:2019:2020-06-27_-_rd_gateway_-_properties_-_transport_settings_tab.png|}}

This seems to be an as of yet unfixed GUI bug: [[https://community.spiceworks.com/topic/2194601-rd-gateway-won-t-let-me-change-https-port-unable-to-set-transport-settings|spiceworks - RD Gateway won't let me change HTTPS Port - Unable to set transport settings]].

You will need to edit these settings directly in the registry.

Example to change the UDP port from 3391 to 3392:
  - Open an elevated PowerShell prompt:
  - View the current settings:<code powershell>Get-Item "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\TerminalServerGateway\Config\Core"</code>
    - Output should look like:<code powershell>Name                           Property
----                           --------
Core                           AllowNewConnections       : 1
                               CorpName                  : Microsoft
                               HttpIPAddress             : *
                               HttpPort                  : 80
                               HttpsPort                 : 443
                               IsaSupported              : 0
                               IsUdpEnabled              : 1
                               MaxConnections            : 4294967295
                               OnlyConsentCapableClients : 0
                               RAPStore                  : msxml://C:\Windows\System32\tsgateway\rap.xml
                               UdpIPAddress              : *
                               UdpPort                   : 3391
                               RDGConfiguredKDCProxy     : 1
</code>
  - Change the UdpPort value to 3392:<code powershell>Set-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\TerminalServerGateway\Config\Core" -Name UdpPort -Value 3392</code>
  - Check the value of UdpPort:<code powershell>Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\TerminalServerGateway\Config\Core" -Name UdpPort</code>
    - Output should look like:<code powershell>UdpPort      : 3392
PSPath       : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Term
               inalServerGateway\Config\Core
PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Term
               inalServerGateway\Config
PSChildName  : Core
PSDrive      : HKLM</code>
  - Restart the RD Gateway service to apply the change in settings:<code powershell>Restart-Service -DisplayName "Remote Desktop Gateway"</code>
  - Don't forget to change the port on the default Windows Firewall rule as well:<code powershell>Set-NetFirewallRule -DisplayName "Remote Desktop Gateway UDP Listener" -LocalPort 3392</code>
