3. How to Choose the Load Balancing Policy
In most cases, it is suggested that you choose IP address as the load balancing policy. If
you want to use some applications that need high bandwidth, such as the NetAnts,
FlashGet, Net Transport, and other multi-threaded download managers (multi-threaded
download means that it can split a file into several pieces and download the pieces
simultaneously, and merge them together once downloaded), you may choose NAT
session as the load balancing policy to take full advantage of multiple Internet connections¶
bandwidth to increase download speed. Note that even if you choose NAT session as the
load balancing policy, due to that the related download website is busy or there are some
other reasons, the bandwidth of each Internet connection cannot be aggregated fully, so
some applications may be not running smoothly.
6.3.3 ID Binding
When using multiple Internet connections, if Load Balancing Policy is set to NAT
Session, the NAT sessions of the same application will be assigned to the different
connections, thus some applications (such as online banking, QQ, etc.) cannot be used
normally due to the identity change. We provide ID binding feature to solve this problem:
After you enable ID binding, the Device will assign the NAT sessions of the same
application to the same Internet connection. For example, when a LAN user logs in to an
online banking system, if the first NAT session is assigned to the WAN2 Internet
connection, henceforth all the subsequent NAT sessions of the online banking application
will be assigned to the WAN2 connection until the user logs out.
