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 ZyWALL 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.
