[Ekiga-list] druid keeps reporting symmetric nat

[Christoph Groth]

Dear all,

My box sits behind a configurable NAT router.  The ekiga 2.0.3 druid
complains about symmetic nat.  Consequently I forward UDP ports 5000
to 5100 to my box.  I do not use a local iptables firewall.

But ekiga keeps complaining about symmetric NAT.  Shouldn't it detect
cone nat now?

(I surely know how to forward ports in our router.  I've done that for
my ssh server and it works perfectly.)

I can "call" my box from outside using sipsak, so the ports _are_
really forwarded (see attached snippet of an ekiga log).

Thanks!
Christoph
