Testing WinPcap/Ethereal with single computer and two NICs

Hi,
I would like to use WinPcap sniffer (ethereal) on a single WinXP
computer.
I have 2 network-cards installed on my Windows XP (3com+realtek) and i
can't configure the cards so that etheral will capture events.

It seems that when i'm trying to access each card , i'm accessing
localhost (loopback,127.0.0.1) so winpcap can't capture it .


I would appreciate any help.

my IPConfig is :
