<DIV><FONT size=2>If the two applications run on the same PC, even if bound to
two different IP addresses assigned to two different NICs, the traffic will not
hit the wire at all. The traffic between the two applications is routed directly
by the TCP/IP stack, and will not reach the NIC card.</FONT></DIV>

<P class=MsoNormal>Hello.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I have a scenario where I have multiple NICs installed in
my PC. I have 2 applications running, each bound to a separate NIC/IP
Address and sending UDP traffic between the two applications.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>When attempting to capture this traffic, though, Wireshark
is only capturing broadcasts. Is there some issue when capturing this
type of traffic on the same PC? <o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
