<div>Hi,</div>
<div>I'm investigating some failed test cases of Tahi in our environment.</=
div>
<div>&nbsp;</div>
<div>Network diagram of test case :</div>
<div>&nbsp;</div>
<div>&nbsp;</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbs=
p;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; NUT</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbs=
p;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; |</div=
>
<div>&nbsp;&nbsp; ------------&#43;---&#43;-------- NET3</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbs=
p;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; |</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbs=
p;&nbsp; Router</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbs=
p;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; |</div>
<div>&nbsp;&nbsp; ------------&#43;---&#43;-------- NET5</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbs=
p;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; |</div=
>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbs=
p;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; SGW1</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbs=
p;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; |</div=
>
<div>&nbsp;&nbsp; ------------&#43;---&#43;-----&#43;-- NET2</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbs=
p;&nbsp;&nbsp;&nbsp;&nbsp; |&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp=
;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; |</div>
<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbs=
p; HOST1&nbsp;&nbsp;&nbsp;&nbsp; HOST2</div>
<div>&nbsp;</div>
<div>Host1 is sending ICMP echo request to NUT. SGW1 encrypts this packet (=
into ESP) before sending to NUT.</div>
<div>Using wireshark running on the windows machine, I can see NUT is reply=
ing to ESP packet however the packet is not reaching HOST1 and test fails.<=
/div>
<div>&nbsp;</div>
<div>If I run &quot;ifconfig&quot; while the test is being executed, I dont=
 see any interfaces being created on FreeBSD, so my question is how does Fr=
eeBSD create these network nodes e.g Router,Host1,Host2 etc</div>
<div>&nbsp;</div>
<div>I want to debug the issue and find out where is the reply packet from =
NUT is getting dropped, for which I need to capture packets on&nbsp; &quot;=
Router&quot; interface connected to NET3 or NET5. (and probably even on int=
erfaces of&nbsp; SGW1 and Host1). How can I capture
packets on each of these interfaces?</div>
<div>&nbsp;</div>
