Hi all….It is already connected 
The process was not running.
What I checked before:
All configuration was ok.
So I follow this link :
https://www.thethingsnetwork.org/docs/gateways/troubleshooting/semtech-udp.html#gateway-not-detecte
1 - I check that program is not running see “Ensure the packet forwarder is running”
2 - Then I tried to find what i must to do to run the process.
I found this file: /etc/iot/scripts/lg01_pkt_fwd
And run like this:
/etc/iot/scripts/lg01_pkt_fwd&
After 2, 3 minutes it was connected to TTN.
I hope that this help someone.
Now that is connected, another step…I will try to see some packets traffic
