Explanation

Remote Desktop Protocol (RDP) uses TCP port 3389. When an employee at home connects to their work computer, the connection arrives at the corporate network - meaning the firewall must allow inbound TCP port 3389 traffic to reach the target work computers. UDP port 3389 is incorrect because RDP uses TCP. An outbound rule would not help home users connect inward; the firewall must accept the incoming RDP session on TCP 3389.
