requirement on the WANs. Another feature supported is fail-over
for the WAN ports. If one of the WAN links is down, RX3042H will
direct the traffic destined for the downed WAN port to the still active
WAN port.
The line back up function is another feature supported to ensure
uninterrupted Internet access. When the primary WAN link is down,
the Internet access is automatically switched to the backup WAN
link.

Table 5.6. WAN Load Balancing and Line Back Up
Configuration Parameters
Setting Description
Load Balance Select one of the three available options:
Disable: disable both the WAN load balancing and line
back up functionalities.
Auto Mode: select this option if load balancing is desired.
The algorithm used for the load balancing is weighted
round robin.
Line Backup: select this option if line backup is needed. In
the existing implementation, the primary link is always set
to WAN1 and the backup link is always set to WAN2.
WAN1/WAN2
Bandwidth
Enter the ratio of the traffic amount that you want to
distribute between the WANs. The number should be
between 0 to 100%. For example, 80% for WAN1 and 20%
for WAN2 means 80% of the traffic is directed to WAN1
and 20% of the traffic is directed to WAN2.
Connectivity
Check
Click Enable or Disable radio button to enable or disable
this feature. Connectivity check is used to monitor the
link status for the WAN ports. If this option is disabled,
RX3042H will not perform fail-over; this means that if
one of the WAN links is down, the traffic directed to the
downed link will not be re-directed to the active link. It is
recommended that you keep this option enabled. However,
if the gateway or the specific network device that will be
checked for connectivity does not respond to ping, you
