[Ekiga-list] Cannot register to ekiga.net

[Kevin Wilson <wkevils gmail com>]

Hello,
  I tried to register to ekiga.net (I have an account). I got : "Could
not register" (Globally not acceptable).
After looking in this suggested page:
http://wiki.ekiga.org/index.php/Enable_port_forwarding_manually
I added port forwarding via my router.
My IP address is 192.168.2.100 and I am connected to the Internet via
Edimax wireless router (NAT enabled).
So I added port forwarding thus:

Private IP           Type Port Range
192.168.2.100    udp   5000-5100
192.168.2.100    udp   3478-3479

but this did not help. I still get "Could not register" (Globally not
acceptable).
Any idea?
Am I missing anything here ?

Regards.
Kevin
