Load Balancing & Fault Tolerance Outbound Load Balancing and Failover (Auto Routing)
Example 1
The auto routing policies to be established accordingly:
1.
Always route connections through WAN#1, which is an ADSL WAN link with 512k downstream/512k upstream.
2.
Always route connections through WAN#2, which is an ADSL WAN link with 1.5M downstream/384k upstream.
3.
Route connections with algorithm "Optimum Route".
4.
Route connections based on the current downstream traffic of WAN links.
5.
Route connections based on the total traffic of each WAN link.
Policy table will look like:
Label Algorithm Parameter
WAN1 (512/512) Fixed Check WAN#1
WAN2 (1536/384) Fixed Check WAN#2
By Optimum Route By Optimum Route Check both WAN #1 and WAN
#2
By Downstream By Downstream Traffic Check both WAN #1 and WAN
#2
By Total By Total Traffic Check both WAN #1 and WAN
#2
Note: Labeling the policies alone does not mean the policy has been set up. Configuring WAN link bandwidth must be
done under [System] -> [Network Settings].
