AP remote office offline in the CWE/no tunel

[Martin_Perez]

Intento crear un túnel entre CWE y AP remoto a través de Internet, si tengo comunicación entre AP y CWE a nivel ping y ssh, pero siempre muestra el AP como caído en color rojo, al parecer no se crea el túnel.

I try to create a tunnel between CWE and remote AP via the Internet , if I have communication between AP and CWE ping and ssh level, but always shows the AP as fallen red , apparently the tunnel is not created.

1) is port forwarding configured on the firewall in the HQ (controller location)
2) has the AP the controller IP (external IP) configured to setup the tunnel
3) could you ping from the AP to the external IP of the controller location
4) could you ping from the controller to the external IP of the AP location
4) any information in the controller log
