WAN connected to LAN and WAN interfaces
I have a number of broadband connections I wish to connect on the WAN interfaces on the TL-ER5120. However they are in another building and as such they are plugged into my switch on one cable and therefore are currently plugged into the LAN. Can I take a cable from the switch and plug into the WAN on the TL-ER5120 and configure the WAN ports to see these broadband lines, in effect they would be plugged into the LAN and WAN on the TL-ER5120, hopefully this makes some sense. I have done a diagram to help explain.
