Feature #4510

Allowing the same packet to come in and go out the same face

Description
The issue is about NFD's limitation of not allowing the same packet to come in and go out the same face.
When simulating a wireless network, NFD only allows Interest packets to come in and go out the same face, but not Data packet.
Consider the case of wireless forwarding: a node may only have one ad-hoc WiFi network face, so if it wants to serve as part of the path, it needs to help forward both Interest packets, and Data packets.
This feature is already implemented in #3968, and tested in Fw/AdHocForwarding/SingleNexthop test case.
You must enable this feature with command for PROTO in ether udp; do sudo infoedit -f /usr/local/ndn/nfd.conf -s face_system.$PROTO.mcast_ad_hoc -v yes; done. Download infoedit if you don’t have this command.
If this isn’t working for you, please provide COMPLETE information as requested, including topology, NFD version (commit hash), nfdc face list and nfdc fib list output on the offending node, and tcpdump packet trace. If you miss any item, you’ll be asked to add that information before I could provide further support.

any updates on this? if you cannot reproduce with the latest version of NFD (or ndnSIM), this issue should be rejected.

Let's reject this. The issue was reported by a student from Lixia's course.
- Status changed from New to Rejected
- Is duplicate of Feature #3968: Forward Interest to ad hoc incoming face added
