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.

Spoof WAN MAC 
Address from 
LAN

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 ZyWALL uses the factory assigned MAC Address to identify 
itself on the WAN.
Otherwise, select this option 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. 

Clone the 
computer’s MAC 
address – IP 
Address

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.
