Technical description for port 1723:
The PPTP (Point-to-Point Tunneling Protocol) running on the computer port 1723 is a method of implementation related to the establishment of VPN (Virtual Private Networks). This protocol has neither an encryption nor a confidentiality protection. Primarily, the security service for this protocol is based on what is being tunneled. This service replaces the L2TP (Layer 2 Tunneling Protocol) including IPSec.
This protocol gained its popularity due to its easy configuration. Likewise, this protocol using the communication port 1723 represents the initial VPN protocol that received support from the Dial-Up Networking feature of the Microsoft Windows Operating System environment. The support for this protocol was initiated under the Windows 95 OSR2 platform. It was limited to two outbound concurrent connections.
As a bundled element, the PPTP protocol flowing through the network port 1723 installs the PPTP Server under the Routing And Remote Access Service of the Microsoft Windows system.
The port 1723 based protocol has also recently been distributed to Linux based systems which initially lacked full support for PPTP.
