We have a RDS Server that has all roles installed on single 2008 R2 server. Users connect to it via Remote Desktop Connections on port 3389 internally and externally.
I want to configure to use Remote Desktop Gateway from external so we can close port 3389 to outside world. Where or what do I need to change a part from closing 3389 on Firewall?
When I test using Remote Desktop and configuring RDG in Advanced tab I am not sure if it is connecting on port 3389 or 443. If 3389 is opened on firewall would it try this by default?
