5.3.2 WAN1 and WAN2 (ZyNOS ZyWALL with two WAN ports)
Since ZyWALL 4.00, the WAN screens are organized differently than the previous versions
because it has two WAN ports. Use the WA N1 and WA N2 tabs to configure the WAN1 and
WAN2 ports. These tabs are similar and vary by encapsulation type.
5.3.2.1 Ethernet Encapsulation
Use this screen to configure an Ethernet connection on one of the device’s WAN ports. To
open this screen, click Device Operation > Device Configuration > Network > WAN >
WAN1/2.
RIP Version The RIP Version field controls the format and the broadcasting method of the
RIP packets that the device 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.
Multicast Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group
Multicast Protocol) is a network-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.
