a deployed RED15 loses its contact to the firewall after about three hours of use.
In the firewall it is then displayed as "down". A control shows that the tunnel LED of the RED is still lit.
After a reboot the RED rebuilds the connection and then loses the contact again after 2-3 hours.
We then exchanged the RED with exactly the same result. The RED's is connected to the Internet via a
fixed public IP address via a 20Mbit line.
If the contact is lost he comes back to the reboot of the RED's no longer by itself.
Someone knows this behavior or has an explanation for it.
