Hi,
<div><br>
</div>
<div>I would suggest that you enable the nfd.Forwarder logging component to see what is going on at the NFD level.</div>
<div><br>
</div>
<div>Thanks,</div>

<div dir="ltr">Hi Everyone,
<div><br>
</div>
<div>When using the custom applications provided with the examples (<a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__ndnsim.net_2.4_applications.html-23customer-2Dexample&d=DwMFaQ&c=Cu5g146wZdoqVuKpTNsYHeFX_rg6kWhlkLF8Eft-wwo&r=eI5Bh74ovG-uIXQ5ksQETSPgRFzmJXjIZXneCqw580E&m=gdQsxKp731SqsqYuSGCbIaKzilhsxAFCuRNVHgmFvf0&s=Fkw05yospMkOzR9bi_AHRLLMKCeQSJZYBwvFnyvy2iE&e=" target="_blank">https://ndnsim.net/2.4/applications.html#customer-example</a>),
both CustomApp and Hijacker are installed on the same node (why does that even work?).</div>
<div><br>
</div>
<div>Is it not possible to create a topology like:</div>
<div><br>
</div>
<div>"CustomApp" <---> "ndn_router_1" <---> "Hijacker"</div>
<div><br>
</div>
<div>I have tried using the "Simple Scenario" from <a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__ndnsim.net_current_examples.html&d=DwMFaQ&c=Cu5g146wZdoqVuKpTNsYHeFX_rg6kWhlkLF8Eft-wwo&r=eI5Bh74ovG-uIXQ5ksQETSPgRFzmJXjIZXneCqw580E&m=gdQsxKp731SqsqYuSGCbIaKzilhsxAFCuRNVHgmFvf0&s=q-AlCSkUC2IobLd7PVwz2d4gUNB7DawFb7MxmKZkal8&e=" target="_blank">https://ndnsim.net/current/examples.html</a>
to create three nodes with p2p links between them and then installing "CustomApp" on node_0 and "Hijacker" on node_2 but they cannot communicate.<br>
</div>
<div><br>
</div>
<div>Can anyone help me with this?</div>
<div><br>
</div>
<div>Best regards,</div>
