External extension

Hello

I’ve got a freepbx 13 installation and works perfect with internal conecction.
I’m using zoiper and its works fine, i can receive and do calls perfect, so i thinks that configuration works fine.
Ive got some extencion that works fine too.
The problem is: With my telephone movile , and with conection 4g i can conect with my server but i can not received and send a call. The conection lost after 7 seconds and i 've not get sounds no hear no microphone etc.

So the questions are : Where is the log in freepbx ? , and what i need to do for a external conection? of course no vpn.

Im behind a nat and i open ports like 5061 over tls 100001 to 100005 ( i got 3 extensions).
Whats ports i neeed to open?
Ive do a netstat -apnt / grep asterisk ( sorry an / it’s wrong i know it.)
and my result is :

tcp 0 0 0.0.0.0:5060 0.0.0.0:* LISTEN 1918/asterisk
