Hi,
the Packet-sink at remote host didn't receive any packets.
Anyone kind advice me, is there something wrong with the example or i just missed something here?
Nice to meet you all. I'm quite new here. while exploring the LTE example.
I tried to run the lena-simple-epc.cc, and try to trace the uplink to the remote-host. the sink didn't receive any packets.

Total Rx : 0 bytes
Average throughput: 0 Mbit/sAnyone kind advice me, is there something wrong with the example or i just missed something here?
Thank You.
Best Regards,

The issues is currently i'm using the ns3 version 3.25. the uplink has some problems previously.
after updating to the latest version (currently 3.30) the problem is solved.
Best Regards,
