Configuring the Sticky Balance feature of LRT224

The latest LRT224 firmware version has a new feature for outbound load management called Sticky Balance.  This is available under the System Management > Dual WAN page of your web interface. 
The Sticky Balance feature is ONLY applicable to LRT224.  It will direct packets with the same source IP, destination IP, and specified TCP/UDP port (e.g. port 443) to the same WAN interface subject to a 10-minute age-out window.  This feature is to avoid some web sites rejecting a user’s web session due to two (2) source IP addresses involved in the session.
This article will show you how to enable and configure the Sticky Balance feature of the LRT224.

Step 1:

Some email hosting services provided by Internet Service Provider (ISP) may reject an email transfer session involving multiple source IP addresses coming from the default load balancing behavior of LRT224.  The Sticky Balance feature can be enabled to avoid the potential issue with the email service.  Users have to contact their providers to find out the TCP/UDP ports used by the email service providers.
