Instruction
Round-Robin Even Distribution
Distribute network traffic evenly in turns WAN1, WAN2,
WAN3… automatically.
Round-Robin by Weight
Same as above, but the lines with larger load ratings will
receive more traffic (go to Weight option in section 4-1-2-f
for setup).
Least Connections
Line with smallest number of connections has priority for
new traffic (go to Max Connection option in section
4-1-2-f to configure).
Upload / Download / Total
Traffic Based
The Line with lowest specific traffic ratio will have priority
for new connections. (go to Bandwidth option in section
4-1-2-f to setup traffic options).
Session Based
Line with lowest number of Sessions gets priority for new
connections. (See section 4-1-2-f to configure the
maximum number of sessions).

ISP
If you don’t desire any Load Balancing to be active, you
can select a single configured WAN connection, or not
configure any policies.
NOTE
：
If a connection fails, other modes will be chosen automatically to complete the
transfer.
If the system is set to the Total Traffic mode mentioned above, for example, the system will
detect the traffic on each of the four WAN connections and give the load to the one with lowest
load ratio to ensure the Quality of Service (QoS). No overloading would occur on any single
line while operating. In addition, on a connection that is usually used for a specific application,
you can also limit the load balancing to specific service ports for traffic management
optimization. For example, you can designate FTP connections, which require large file
transmission most of the time, a specific load balancing mode for data transmission.
