ICMP Destination Unreachable, port Unreachable in example code

[Alpha]

I am trying to simulate the wifi-wired-bridging.cc example code after making the necessary changes as mentioned in https://www.nsnam.org/bugzilla/show_bug.cgi?id=2083 .
I am seeing ICMP Destination Unreachable,port unreachable. I am attaching the wireshark capture. Can anybody please help me out on this ??

No.

I would if I could. Much like in the Paul Simon's song.

Yes I would
If I only could, I surely would.

Why I can't ? Well, this is the important part.

However, I'll leave it to your imagination. If you're smart enough, you'll find out why I can't (and nobody else can).

Have fun,
