[asterisk-users] SIP trought Firewall

[Emiliano Vazquez]

Hi to everyone!

I have succerfully instaled my new Asterisk 1.4 on my debian etch.

I have my users in sip.conf like this:

[200]
type=peer
host=dynamic
context=home
secret=200
callerid= 200
dtmfmode=rfc2833
nat=yes
mailbox=200 at home
disallow=all
allow=ulaw

I can make calls in my LAN but i can´t ear comunications with another client 
trought Internet.
My Asterisk is in my LAN and i not have a DMZ. I search in the list and find 
something about "rtp" ==> rtp.conf. I found rtpstart and rtpend and forward 
those Ports on my firewall, but this don´t work for me.

What´s wrong???

If you need some info please tell me.

Thanks in advance!

Emiliano Vazquez.
