WAN Affinity and Load Balancing

WAN affinity and load balancing both require multiple WAN devices, which is not typical usage
LOAD BALANCE
Select the Load Balance Algorithm from the following
dropdown options:
• Round-Robin: Evenly distribute each session
to the available WAN connections.
• Rate: Distribute load based on the current upload and download rates. A WAN device's upload and download bandwidth values
can be set in Internet → Connection Manager.
• Spillover: This was the default algorithm in older (version 3) firmware. Load is always given to devices with the most available
bandwidth. The estimated bandwidth rate is based on a combination of the upload and download configuration values and the
observed capabilities of the device.
• Data Usage: This mode works in concert with the Data Usage feature (Internet → Data Usage). The router will make a
best effort to keep data usage between interfaces at a similar percentage of the assigned data cap in the Data Usage rule for
each interface, rather than distributing sessions based solely on bandwidth. For proper function you need to create data usage
rules for each WAN device you will be load balancing. Make certain to select the "Use with Load Balancing" checkbox in the
Data Usage rule editor.
WAN AFFINITY
WAN Affinity rules allow you to manage traffic in your network so that particular bandwidth uses are associated with particular WAN
sources. This allows you to prioritize bandwidth.
EXAMPLE: You could specify that your guest LAN is only associated with your Ethernet connection with no failover. Then if your Ethernet
connection goes down and the embedded modem connects for failover for your primary LAN, your guest LAN will not take bandwidth from your
primary LAN, saving you money.
Click "Add" to open the WAN Affinity Policy Editor and create a new WAN Affinity rule.
Name: Give a name for your rule that is meaningful to you.
