ZyWALL 2WG User’s Guide

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.

Enable Multicast

Select this check box to turn on IGMP (Internet Group Multicast Protocol). IGMP is 

a network-layer protocol used to establish membership in a Multicast group - it is 

not used to carry user data.

Multicast Version Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group Multicast 

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.

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 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. 

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.
