traffic

i hope someone can help me out with somewhat simple task. I'm trying to redirect a client in my router through my desktop PC, so i can dump the traffic and analyze it (its potential source of poisoning the network with malicious packets). However i don't have a second NIC on my hands and i was hoping i can redirect all the traffic from that IP through my PC. In essence to become MITM for the client. Does anyone have any idea where to start:

Current state:

(localip)->(router)->(internet)

And what i want to do:

(localip)->(pc)->(router)->(internet)
