[asterisk-users] Asterisk and NAT ?

[Noc Phibee]

Hi

I am search a small information

- i use Asterisk on official IP without Nat

- My first VoIP phone are a Thomson 2030 on a NAT Network.
   That's work very good.


But now, i want add a second phone, a Linksys SPA-941 on
the same network of the Thomson 2030 ...

My problems that i don't see a solution into asterisk or
on my firewall for that's work.

When i call to the thomson, that's work, when i call to the linksys
that's don't ring ...

On my asterisk i have put :
200= thomson
202= linksys


[200]
port=5060
username=200
secret=X
type=friend
host=dynamic
disallow=all
allow=g729
allow=alaw
allow=ulaw
context=interne
qualify=yes
nat=route
dtmfmode=rfc2833
language=fr


[202]
port=5070
username=202
secret=X
type=friend
host=dynamic
disallow=all
allow=g729
allow=alaw
allow=ulaw
context=interne
nat=route
dtmfmode=rfc2833
language=fr



on my firewall, i have put a forward of port 5060 to thomson and 5070 to 
linksys
in UDP and TCP.

On linksys i can call but not receive call
on thomson i can call and receive without problems

Thanks for your help
