Hi,
I've successful run ns-3-dce (1.5), with dce-iperf-mptcp example, thanks to Hajime and Micchio Honda guidance.

However, in the collected trace, I saw crossed-traffic between node0-sim0 and node1-sim1, as well as between node0-sim1 and node1-sim0. This is undesirable for me.

More suprising, in *-0-0.pcap, there's traffic from node1-sim0 to node0-sim1. 

              10.1.0.1  ---------------------- 10.2.0.1
                              - \    /-----------
Node0                      \/                          Node1
                                _/ \_______
              10.1.1.1  ------------------------ 10.2.1.1

You can download the trace from dropbox, I merged trace with mergecap at each node already.

(Then I tried using iptables to block traffic. iptables build successed but not able to load into simulation)

Thank you for your help.
Hoang
