    <div class="moz-cite-prefix"><tt>Hello Gary,<br>
        <br>
        As functionality there is a big resemblance between the two
        modules. Still there are differences (nat_traversal is more
        session aware, while nathelper is more low-level and flexible as
        usage).<br>
        <br>
        Regards,<br>
