Is there any particular reason you are working with that version?
It's *extremely* old now (having been released over 2 1/2 years ago),
and the 5.1.x line has now been mothballed.
   It's not even the most recent version on that line, since 5.1.4
was released back in March this year.   We would *strongly*
encourage you to use 5.1.4 (at the very least).  And preferably one
of the more recent releases, on a line that is still being maintained.

The latest release is currently 5.3.1, with 5.4 due imminently.

This is a bug, that I'm pretty sure was fixed some time ago.
The current code certainly handles this properly (though it
appears v5.1.4 still suffers from the same problem).

Note that the handling of transport addresses changed significantly with
the v5 code, and use of the 'remote_port' field is no longer recommended.
Ideally, we would have removed this field altogether, but that would
obviously have broken any existing software that relied on it.

Try upgrading to a newer version (e.g. 5.3.1 or the upcoming 5.4).
