Port 3389 is used for Remote Desktop Protocol (RDP), which is primarily used by Windows systems for remote management. Since the Windows servers no longer exist and the remaining servers run Linux, this rule is unnecessary. Ports 53, 443, and 80 are commonly used for DNS, HTTPS, and HTTP respectively, which are protocol services likely still needed by the Linux servers.
