asterisk users - Dec 2004 - Ticket: 12775 Multiple IAX client behind a NAT

Hello!

I have a number of IAX clients behind a NAT (on the same LAN) and
asterisk server on the Internet. And that clients doesn't speak directly
to each other, traffic goes through the asterisk server.
What should I configure to make IAX clients on the same LAN to speak
directly, please?

notraster=no is set in iax.conf

The asterisk server is on real IP behind a NAT (at DMZ with full 1-to-1 
port forwarding).

The client are behind a PAT (Samsung adsl modem-router).

"iax2 show peers" shows:
