5.3 WAN General (ZyNOS ZyWALL)
This section gives configuration information on the fields displayed in this screen. To open
this screen, click Device Operation in the menu bar, and click Device Configuration >
Network > WAN > General in the navigation panel.
" Be careful when configuring a device’s WAN as an incorrect configuration
could result in the device being inaccessible from Vantage CNM (or by the web
configurator from the WAN) and may necessitate a site visit to correct.
IP Subnet Mask The device automatically calculates the subnet mask based how many aliases
you select. See also the appendices for more information on IP subnetting.
RIP Direction RIP (Routing Information Protocol, RFC1058 and RFC 1389) allows a router to
exchange routing information with other routers. The RIP Direction field controls
the sending and receiving of RIP packets. Select the RIP direction from Both/In
Only/Out Only/None. When set to Both or Out Only, the device broadcasts its
routing table periodically. When set to Both or In Only, it incorporates the RIP
information that it receives; when set to None, it does not send any RIP packets
and ignores any RIP packets received.
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).
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, RIP direction is set to Both
and the Version set to RIP-1.
