<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>
<p class=MsoNormal>Best Regards,<o:p></o:p></p>
