PPTP VPN uses which port?

Explanation:
PPTP VPN uses TCP port 1723 for the control connection that starts the tunnel; the actual data is carried inside GRE, not another TCP/UDP port. The other numbers correspond to different services (21 is FTP, 3389 is RDP, 25 is SMTP), so they aren’t used by PPTP. So the port associated with PPTP is 1723.
