DESCRIPTION
Type the first (primary) phone number from the ISP for this remote
node. If the primary phone number is busy or does not answer, your
device dials the secondary phone number if available. Some areas
require dialing the pound sign # before the phone number for local
calls. Include a # symbol at the beginning of the phone numbers as
required.
Type the AT command string to initialize the WAN device. Consult the
manual of your WAN device connected to your dial backup port for
specific AT commands.
Click the Edit button to display the Advanced Modem Setup
screen and edit the details of your dial backup setup.
Network Address Translation (NAT) allows the translation of an
Internet protocol address used within one network to a different IP
address known within another network.
SUA (Single User Account) is a subset of NAT that supports two
types of mapping: Many-to-One and Server. When you select this
option the device will use Address Mapping Set 255 in the SMT.
Select this check box to turn on RIP (Routing Information Protocol),
which allows a router to exchange routing information with other
routers.
RIP (Routing Information Protocol) allows a router to exchange
routing information with other routers. The RIP Direction field
controls the sending and receiving of RIP packets.
Choose Both, In Only or Out Only.
When set to Both or Out Only, the device will broadcast its routing
table periodically.
When set to Both or In Only, the device will incorporate RIP
information that it receives.
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.
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.
