You can configure route advertisements for each Interface/zone by clicking on the Notepad icon in the Configure column of Route Advertisement table, which displays the Route Advertisement Configuration window. I am wondering about how to setup LAN_2. I added a "LocalAdmin" -- but didn't set the type to admin. network traffic traverses the switch, the traffic is also sent to the mirrored port and from there into the SonicWALL for deep packet inspection. Asking for help, clarification, or responding to other answers. Why are non-Western countries siding with China in the UN? The following are sample topologies depicting common deployments. other traffic types, such as IPX, or unhandled IP types. Bridge Mode that is used for intrusion detection.
