6.8.3 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.

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 configure the WAN port's MAC address by either using the factory
assigned default MAC Address or cloning the MAC address of a computer on your
LAN. By default, the ZyXEL Device uses the factory assigned MAC Address to
identify itself on the WAN.
Otherwise, select the check box next to Spoof WAN MAC Address from LAN 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.
If you clone the MAC address of a computer on your LAN, it is recommended that
you clone the MAC address prior to hooking up the WAN port.
Click Apply to save your changes.
