My EOC-3660 died so I was running DD-WRT on WRT54G client bridge. My Actiontec DSL modem/router saw the MAC addresses of clients behind WRT54G and assigned them DHCP.
The 5611P, in client bridge mode, shows the router the same (its) MAC address for different IPs. I tried another DSL router (Westell 7500) just for kicks, but it assigns the same MAC address to all IPs coming from that bridge. As thus, a router will not assign DHCP to anything past the bridge.
I am having to run 5611P in client router mode to get DHCP for my smartphones and tablets. :/
Back to the main point: will putting dd-wrt on the 5611P show my headend router the correct MAC addresses, as a layer 2 device should?
