Metric
This field sets this route's priority among the routes the ZyXEL Device uses.
The metric represents the "cost of transmission". A router determines the best
route for transmission by choosing a path with the lowest "cost". RIP routing uses
hop count as the measurement of cost, with a minimum of "1" for directly
connected networks. The number must be between "1" and "15"; a number greater
than "15" means the link is down. The smaller the number, the lower the "cost".
Enable SUA
Select this if you have one public IP address and want to use NAT, or clear it to
disable NAT.
Enable RIP
Select this if you want to enable RIP in the dial-backup connection. RIP (Routing
Information Protocol, RFC 1058 and RFC 1389) allows a router to exchange
routing information with other routers. Clear this if you want the ZyXEL Deviceto not
send any RIP packets and to ignore any RIP packets received.
RIP Version
The
RIP Version
field controls the format and the broadcasting method of the RIP
packets that the ZyXEL 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.
RIP Direction
The
RIP Direction
field controls the sending and receiving of RIP packets. Select
the RIP direction from
Both
/
In Only
/
Out Only
. When set to
Both
or
Out Only
, the
ZyXEL Device will broadcast its routing table periodically. When set to
Both
or
In
Only
, it will incorporate the RIP information that it receives.
Enable Multicast
Select this if you want to enable IGMP in the dial-backup connection. IGMP
(Internet Group Multicast Protocol) is a network-layer protocol used to establish
membership in a multicast group.
Multicast
The ZyXEL Device supports both IGMP version 1 (
IGMP-v1
) and
IGMP-v2
.
PPP Options
Encapsulation
Select
CISCO PPP
from the drop-down list box if your dial backup WAN device
uses Cisco PPP encapsulation, otherwise select
Standard PPP
.
Compression
Select this to turn on stac compression.
Connection
Nailed-Up
Connection
Select
Nailed-Up Connection
when you want your connection up all the time. The
ZyXEL Device will try to bring up the connection automatically if it is disconnected.
Connect on
Demand
Select
Connect on Demand
when you don't want the connection up all the time
and specify an idle time-out in the
Max Idle Timeout
field.
Max Idle Timeout Specify an idle time-out in the
Max Idle Timeout
field when you select
Connect on
Demand
. The default setting is 0, which means the Internet session will not
timeout.
Budget
Allocated Budget
Enter the maximum amount of time (in minutes) each call can last. Enter 0 if there
is no limit. With
Period
, you can set a limit on the total outgoing call time of the
ZyXEL Device within a certain period of time. When the total outgoing call time
exceeds the limit, the current call will be dropped and any future outgoing calls will
be blocked.
Period
Enter how often (in hours) the
Allocated Budget
is reset. For example, if you can
call for thirty minutes every hour, set the
Allocated Budget
to 30, and set this field
to 1.
