9.4 The 3G (WAN2) Screen
Use this screen to configure your 3G (WAN2) settings.
After you insert a 3G card in the ZyWALL 5, the 3G connection becomes WAN 2. Refer to
for the type of 3G cards that you can use in the ZyWALL along with
the corresponding supported features.
RIP Version
The RIP Version field controls the format and the broadcasting method of the RIP
packets that the ZyWALL sends (it recognizes both formats when receiving).
packets that the ZyWALL sends (it recognizes both formats when receiving).
Choose RIP-1, RIP-2B or RIP-2M.
RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is
probably adequate for most networks, unless you have an unusual network
topology. Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the
difference being that RIP-2B uses subnet broadcasting while RIP-2M uses
multicasting. Multicasting can reduce the load on non-router machines since they
generally do not listen to the RIP multicast address and so will not receive the RIP
packets. However, if one router uses multicasting, then all routers on your
network must use multicasting, also. By default, the RIP Version field is set to
RIP-1.

Enable Multicast
Select this check box to turn on IGMP (Internet Group Management 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
Management 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 inter-
operability between IGMP version 2 and version 1, please see sections 4 and 5 of
RFC 2236.

Spoof WAN MAC
Address from LAN
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.
