Enable the Return to Ethernet Sender Mode
This mode allows multiple routers to share an appliance. The appliance forwards virtual inline output packets back to where they came from, as indicated by the Ethernet address of the incoming packet. If two routers share a single appliance, each gets its own traffic back, but not the traffic from the other router. This mode also works with a single router. To enable the Return to Ethernet Sender mode by using the configuration utility
- Navigate to the System > Network page.
- Click the Configure Layer 2 Parameter link, as shown in the following figure.
- In the Configure Layer 2 Parameter dialog box, select the Return to Ethernet Sender option, as shown in the following figure.
- Click OK.
To enable the Return to Ethernet Sender mode by using the command line interface, run the following command
``` pre codeblock
set L2Param -returnToEthernetSender ENABLED ```
