8.7.3 PPTP 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 screen shown next is for PPTP encapsulation.

DESCRIPTION
Protocol) is a session-layer protocol used to establish membership in a Multicast
group – it is not used to carry user data. IGMP version 2 (RFC 2236) is an
improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If
you would like to read more detailed information about interoperability between
IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.
You can use the factory assigned default MAC Address or cloning the MAC
address from a computer on your LAN.
Otherwise, select the check box next to Spoof WAN MAC Address and enter the
IP address of the computer on the LAN whose MAC you are cloning. Once it is
successfully configured, the address will be copied to the rom file (ZyNOS
configuration file). It will not change unless you change the setting or upload a
different ROM file.
Enter the IP address of the computer on the LAN whose MAC you are cloning.
It is recommended that you clone the MAC address prior to hooking up the WAN
port.
