Hi,

can you make this change in the forwarder.cpp file of NFD?

https://github.com/4th-ndn-hackathon/ndnSIM-Mobile-Simulation-Package/commit/cadcfc41ff1b6bed617f700f822507c4dcd0f63c <https://github.com/4th-ndn-hackathon/ndnSIM-Mobile-Simulation-Package/commit/cadcfc41ff1b6bed617f700f822507c4dcd0f63c>

Thanks,

I used “Nqos Wifi Mac helper” for configuring the Mac model.

When I enable the log I can see that my interest goes through from node 0 to node 1, and from node 1 to node 2, and node 2 gets satisfied, and node 2 sends the data back to node 1, but node 1 never receives the data. Node 1 and 0 are unsatisfied. I was wondering why node 1 is not getting the data back?
