Table 36   PPTP Encapsulation

ISP Parameters for Internet Access

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 ZyXEL Device supports only one PPTP 

server connection at any given time. 
To configure a PPTP client, you must configure the User Name and 

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

connection.
