sniffing

I have a TG585v7 as a router with several machines plugged into it. In the default setup, the packets are only delivered to the specific machine but I want to be able to setup to monitor all network traffic on one of the machines, i.e. I need those packets to be picked up when my ethernet card is in promiscuous mode. Is this possible?

Guide here has this "mcastpromisc Make the IP interface multicast promiscuous. OPTIONAL", is this what I am looking for? Does it mean I need to manually add all my machines by their MAC addresses to be able to receive packets destined for them? Or am I out of luck and I need to get a better router?
