I have installed RDP gateway on windows server 2019 and went through the configuration. I was unable to disable UDP 3391 transport in RDP Gateway windows server 2019
I tried it on 2 separate windows 2019 servers that used the normal install and no GPOs.
Any idea how to get it to turn off. We do not want to use UDP 3391 due to the port being blocked throughout the enterprise.
It is disabled In windows server 2016 by default. I actually would get the same error if I tried to enable it in windows server 2016. But for the scope of the question, We are trying to disable it in 2019.
