[Ekiga-list] quick help appreciated: ekiga always report symmetric NAT even after port-forwarding enabled.

[Zhang Weiwu <zhangweiwu realss com>]

   1.  If I set my notebook as DMZ, ekiga report I have cone NAT and
      thus should work. But I cannot keep my notebook as DMZ for local
      network management reasons;
   2. If I don't set my notebook as DMZ, ekiga always report I have
      symmetric NAT even if I enable port-forwarding strictly according
      to recommendation;
         1. router (act as NAT firewall) setting is attached to this
            email. Note 192.168.1.101 is IP address of my notebook;
         2. there is only 1 public IP address for this router;
         3. router setting is tested using netcat (running 'nc -u -l -p
            5062' on my notebook and run 'nc -u emerson.realss.com 5062'
            on a remote server, test UDP port forwarding works fine by
            typing hello world on remote server and see it comes out
            locally);


Fast help highly appreciated because I am trying to start an online meeting.
