</div>Yes, it is currently limited to the responder address, so only<br>
host-to-host tunnels are possible. You might change TSr at [1] and use<br>
traffic_selector_create_from_subnet() or something. It's not supported<br>
because I've never used it, and extending it properly for initiator and<br>
responder support requires some work.<br></blockquote><div><br>So it is likely that adapting [1] is not enough?<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

</div>Probably because your responder configuration does not except a<br>
host-to-host tunnel.<br></blockquote><div><br>What exactly do you mean? A possible missconfiguration on server-side?<br>Can you please elaborate?<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

<br>
</div>If you want to test net-to-net/host-to-net tunnels, yes. But usually the<br>
same TSr for all clients is fine as long as you have a different TSi.<br></blockquote><div><br>This is in general correct for traffic initiated from B-side.<br>But when traffic is initiated from A-side and TSr is <a href="http://0.0.0.0/0">0.0.0.0/0</a> for all tunnels, then it will choose only one interface (most likely the one with smaller IP). Unless, you can instruct any traffic generator tool to use a specific IP.<br>
