    <div class="moz-cite-prefix"><tt>Hi George,<br>
        <br>
        nathelper module is used for multiple purposes like:<br>
            1) nat pinging<br>
            2) manging SIP signaling.<br>
        <br>
        If you are sure your clients are doing the pinging and you do
        not any signaling manging (fixing contacts, etc), you can stop
        using the nathelper module.<br>
        <br>
        Regards,<br>
      </tt>

        <div>do i need nathelper if my client keeps pinging all the
          time?<br>
          <br>
          What's the use of those two method? I think we should always
          use<br>
          5060 or 5061, otherwise how can you reach the client behind
          nat?<br>
