Encapsulation

Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables

 

secure transfer of data from a remote client to a private server, creating a Virtual

 

Private Network (VPN) using TCP/IP-based networks. PPTP supports on-

 

demand, multi-protocol, and virtual private networking over public networks, such

 

as the Internet. The ZyWALL supports only one PPTP server connection at any

Password fields for a PPP connection and the PPTP parameters for a PPTP

 

connection.
