Routing the Default & Secondary Default Gateways
Because the gateway address objects previously associated with the Primary WAN and Secondary WAN are now deprecated, user-configured Static Routes need to be re-created in order to use the correct gateway address objects associated with the WAN interfaces. This will have to be configured manually as part of the firmware upgrade procedure.
The old address object Default Gateway corresponds to the default gateway associated with the Primary WAN in the LB group. The Secondary Default Gateway corresponds to the default gateway associated with Alternate WAN #1.
