Asterisknow behind nat


I am trying to place my asterisknow (1.7.0) + FreePBX behind nat…

I configured my firewall to allow access to my public IP: all Ports for UDP and TCP port 5060 only for TCP

now, I able to do outbound call from internet, but the call always rejected after the 1st ringing…

what should I check?

please advise

Thanks & Regards

please ignore this and I just want to share for a newbie like me :->)

this can be done by:

Tools -> Asterisk SIP Settings -> NAT = Yes, IP Configuration = Static IP, External IP = enter_your_public_ip_here, Local Networks = enter_your_asterisk_ip_here / subnetmask

hmm nice toys … good luck :->)
