SYNOPSIS
pptp server [options]
DESCRIPTION
pptp establishes VPN connections using the Point-to-Point Tunneling Protocol. It creates an encrypted tunnel to a remote PPTP server by wrapping PPP sessions inside GRE (Generic Routing Encapsulation) packets, allowing secure communication over the internet.
The client works in conjunction with pppd which handles the PPP negotiation and authentication within the tunnel. PPTP is considered a legacy protocol with known security weaknesses, and modern alternatives like OpenVPN or WireGuard are recommended for new deployments.
