[Help] How to capture all the traffic that goes through my router

Hi everybody,

Currently, i have my desktop pc(192.168.2.3) which connects to my router (192.168.2.1) on eth1 with ethernet cable as well.
Desktop OS: Backtrack 5r3

Also, i have a laptop (192.168.2.2) which connects to my router (192.168.2.1)
on wlan0 via wireless.
Laptop OS: Backtrack 5r3

When im on desktop, I open wireshark --> Interface list (here is the place to set the device that you want to capture) , i add the eth1 to capture the traffic of my desktop.
If i want to capture both (desktop and laptop traffic) i add eth1 and wlan0 and i can see the traffic without problem.

Here is the question:

When im on the laptop i can easily capture the traffic of LAPTOP only by adding wlan0 in Interface list.

How can i capture the whole traffic that goes through my router (192.168.2.1) ??

I've done a research around the web and i think that i have to do something related with the SSH (port 22).

Can anyone help me with that?

Any post is welcome!

Thanks!
Open wireshark and don't set any limiting filters. That'll capture everything leaving and entering your router
For that , WireShark may help you ..
You just to select the Ethernet controller ..
