I can not connect to my sip provider?

Hello and thank you for your help.

What port forwarding are you talking about ? I just have the computer with freepbx in the dmz on the router.

I have put what you said in peer and user and added externip=xx.xx.xx.xx on peer and user

and i have that on the cli :
