As discussed earlier in the Remote Desktop Services (2.3.3) section, port 3389 is used by RDS to send and receive data. However, that is for accessing one computer at a time. What happens when you try to access more than one computer simultaneously with RDS? While the first computer is using port 3389, sequential port numbers are assigned to other computers on the LAN starting with 3390. That way, to access multiple computers simultaneously from a remote location over the internet, we use an IP socket. An IP socket is a combination of an IP address and a port number and tells the application where data should be delivered.
- Syntax: Public_IP_address:Port_number
- Example: 192.168.2.10:8080
