PPTP

 

POINT-TO-POINT TUNNELING PROTOCOL (PPTP)

• PPTP ALLOWS MULTIPROTOCOL TRAFFIC TO BE ENCRYPTED AND THEN ENCAPSULATED IN AN IP HEADER TO BE SENT ACROSS AN IP NETWORK OR A PUBLIC IP NETWORK.

• PPTP CAN BE USED FOR REMOTE ACCESS AND SITE-TO-SITE VPN CONNECTIONS.

• PPTP ENCAPSULATES PPP FRAMES IN IP DATAGRAMS FOR TRANSMISSION.

• PPTP USES A TCP CONNECTION FOR TUNNEL MANAGEMENT AND A MODIFIED VERSION OF GENERIC ROUTING ENCAPSULATION (GRE) TO ENCAPSULATE PPP FRAMES .

• THE PAYLOAD OF THE ENCAPSULATED PPP FRAME CAN BE ENCRYPTED, COMPRESSED OR BOTH.
