Are you sure packets are actually transmitted on the wire/wireless and not just routed internally by the IP stack?

Subject: [Wireshark-users] Capturing packets between 2 physical interfacesin same machine

Hi-
 
I just installed Wireshark version 0.99.5 on Windows XP.
 
My laptop has 2 interfaces - ethernet & wireless LAN. I want to capture packets sent between the 2 interfaces. I tried capture on either interface with default settings (promiscuous on), but I see only packets received from other hosts.
 
I could understand that packets sent between loopback addresses cannot be captured. But, I was hoping that capture between multiple physical interfaces would work. Any idea why this does not work?
 
Regards,
Nagaraj
