Capturing traffic from another machine coming on Ethernet network adapter using ics

[Prashant choudhary]

I have two machine. Machine A is connected to internet using wireless adapter and fiddler is running on this machine.

Machine B  is connected to machine A using LAN  cable accessing internet from machine A using ICS.

On Machine B, I can not install any software which can redirect the traffic to machine A on port 8888.

I want to capture the traffic coming from Machine B on Machine A using fiddler. 

Is there any way using which I can capture the traffic coming from Machine B? I tried couple of things but not able to find any good way.

Please help.

What traffic do you hope to capture?

You don't need to "install any software" in order to manually reconfigure Machine B's proxy settings to point at Fiddler running on Machine A.
