asterisk users - Oct 2010 - 1 way audio asterisk 1.6

Hi
?
I ?wonder if?anyone could give some light on SIP NAT.
I've having a friken headache with SIP NAT 1 way audio.
Client - NAT? - NAT - Server
Client can hear users from server side
but server cant hear client.
?
Ive tried every possible settings 
externip set
localip set
NAT= yes / route 
directmedia yes/ no
?
Ive check the sip headers in the debug mode and its using the external address 
in both client and server.
?
Ive tried STUn servers etc
?
No luck. any info on this
Its for my installation which I am testing.
?

The more detail you post, the more chances are there to get help. For
example here you should have posted your sip.conf, devices used, and
probably also the context doing the communication.
