What port is 3389 used for?

Port 3389 is used to enable users to access remote computers. While in most cases this access is legitimate and approved by the owner of the physical machine, there are also port 3389 vulnerabilities that make it critical to limit access.

Does RDP use port 443?

To access your server via RDP on port 443, you either have to use RRAS to redirect port 3389 traffic to port 443 or reconfigure Terminal Services to use port 443 instead of port 3389.

Why is port 8080 default?

"8080" was chosen since it is "two 80's", and also because it is above the restricted well known service port range (ports 1-1023, see below). Its use in a URL requires an explicit "default port override" to request a web browser to connect to port 8080 rather than the http default of port 80.
