asterisk users - Jan 2009 - Don't get asterisk to run behind NAT router

Hi people!
I am not getting smart getting asterisk 1.6  behind a NAT to run.

1. I enabled IP forwarding on debian linux
2. told asterisk in "general" that he is behind NAT and mentioned him
his external static IP Adress as well his domain in the outside world.

If a client who is connected with a DSL modem calls me, a grandstream
module in the LAN behind the router, in the same network asterisk is
running at, takes the call. but we can't hear / talk with each other.


Ay ideas to get this thing solved?!



My general section in sip.conf:

[general]
port=5060
bindaddr=0.0.0.0
localnet=192.168.1.0/255.255.255.0
externip=85.183.112.3
externhost=voipfax.higazi-it.com
allowtransfer=yes
qualify=yes
nat=yes

[2006]
type=friend
secret=frank
host=dynamic
context=nurintern
nat=no

[2007]
type=friend
secret=jochen
host=192.168.1.2
context=nurintern
nat=yes

Hi Tamer
Try to configure canreinvite=no or canreinvite=nonat.

Regards
Dimitar

You enabled port forwarding, but have you actually forwarded any ports ?
Defaults are
tcp 5060
udp 10000-20000
