Ok, i see I can't intercept packets when im not in the middle. So how do i go about and setup a TCPdump on a router?

Hi, i have been using Wireshark for a few days now. I have been able to see what other people are doing on the internet when they are connecting trow my computer by using an ethernet cable. How would i do this without me being in the middle? So i could intercept packets from other computers on other networks. Can i do this in Wireshark or not, if not how can I? Thanks, DJM
