hi all; i am now able to register my client with the openserver server.
i used STUN server option of x-lite and stun.voipuser.org as the stun server i also set/exported SIP_DOMAIN variable to my public openser server ip address.
i wonder do i have to use a stun server ?

hi; i installed and tested openser on the internal network, it was working. i tried to test it behind NAT with x-lite sip client, but it failed.
i defined a port mapping on the adsl modem for udp/tcp 5060 ports to forward the packets to the openser installed machine. when i try to register to openser i received a 408 request timeout message.
i guess its due to external ip of the openser server. i think i should define external ip of the modem to the openser as if it's its own ip, but dont where to define it.
here is the ngrep dump at the server.
