Protocol binding addresses two issues:
• Segregation of traffic between links that are not of the same speed.
High-volume traffic can be routed through the WAN port connected to a high-speed link,
and low-volume
traffic can be routed through the WAN port connected to the low-speed
link.
• Continuity of
source IP address for secure connections.
Some services, particularly HTTPS, cease to resp
ond when a client’s source IP address
changes shortly after a session has been established.

Load Balancing Mode radio button.
b. From the co
rresponding drop-down list on the right, select one of the following load
balancing methods:
• W
eighted LB. With weighted load balancing, balance weights are calculated
based on WAN link speed and available WAN bandwidth. This is the default
setting and most efficient load balancing algorithm.
• Round-robi
n. With round-robin load balancing, new traffic connections are sent
over a WAN link in a serial method irrespective of bandwidth or link speed. For
example, if the WAN1, WAN2, and WAN3 interfaces are active in round-robin load
balancing mode, an HTTP request could first be sent over the WAN1 interface,
then a new FTP session could start on the WAN2 interface, and then any new
