Sonic OS 2.x Quick Start Guide

WAN Load Balancing

As previously mentioned, the Load Balancing capability can be Active-Passive, or Active-Active. If you decide to use the Active-Active option, you will select one of the three load balancing algorithms.

Round Robin	The Sonicwall balances the outgoing
	traffic on a per-destination basis by
	examining source and destination IP
	addresses.
Spill Over	The Sonicwall balances the outgoing
	traffic on a spillover basis when a
	bandwidth maximum is reached on
	the Primary WAN. You must specify
	the maximum bandwidth to use on
	the Primary WAN before traffic is sent via the Secondary WAN.
Percentage	The Sonicwall balances the outgoing traffic on a percentage basis of the total
	bandwidth available on the two WAN links. You must specify the percentage of
	bandwidth for the Primary WAN link and the Sonicwall automatically allocates the
	remaining percentage to the Secondary link.

1.From the GUI, select the type of Load Balancing that fits your customer’s needs.

2.For other than Round Robin, enter the appropriate bandwidth amount or spillover percentage.

3.Don’t forget to click the Apply button at the top of the page!

NOTE – Before the load balancing is complete, you must create a NAT rule for the second WAN interface.

4.From the GUI, select the Network button and then the NAT Policies option.

5.Click the ADD button.

6.For Original Source, select LAN Subnets. We need to NAT any LAN traffic outbound through the Secondary WAN.

7.For Translated Source, select X2 IP. NAT outbound traffic to the dynamic PPPoE IP of the Secondary WAN.

8.For Original Destination, select ANY. Any traffic destined for the Internet.
