PPTP Network Server (PNS)
A device which provides the interface between the Point-to-Point Protocol (encapsulated in the PPTP protocol) and a LAN or WAN. The PNS uses the PPTP protocol to support tunneling between a PPTP Access Concentrator and the PNS. As described in an IETF draft document on PPTP, a PNS is expected to run on a general purpose computing/server platform. See Point-to-Point Tunneling Protocol. (See Point-to-Point Protocol, encapsulation, LAN, WAN, and IETF in the hard copy dictionary.)
