WAN Load Balancing 1-13
Software Version 2.7.5
C613-10454-00 REV A
Configuration Examples
The following examples illustrate the steps required to configure WAN load
balancing on the router.
This example shows a load balancer where data travels to remote destinations
via two Internet connections, each routed via a separate ISPs. A simple firewall
configuration is also included that provides for basic network address
translation (NAT). This configuration will load balance data from different
devices regardless of the session types that they are running, and data from the
same device on a session type basis. So a data packet for an HTTP session
followed by a data packet for a TFTP session transmitted from the same device
would be routed via alternate ports.
